Welcome to my Blog,

Latest Improvements:   December, 2019

Latest Improvements to our Biophysica Generators:   December, 2019 (These improvements apply to our commercial units and to a certain degree to our domestic units  )

Pictured below, Biophysica’s new High-Voltage, High-Power Commercial two channel Generator.

1) Power and Ohm’s law: We have upgraded the supply voltage of our commercial models from 48v to 140v in order to more effectively process highly purified low conductivity water (such as distilled water, RO, etc.) and to significantly speed up the commercial production of large volumes. These new advanced models feature constant current which can be adjusted by the operator within the range 15-300 milliamperes.

Another improvement in our design allows for adjusting the distance between the electrodes which gives yet, more flexibility in achieving the desired target current depending on the type of water available.

Higher currents are available in our industrial models for swimming pools, cooling towers, hospitals and hotels, cattle, poultry and fish farms.

2) Meter: We have included a new digital meter on the front panel of the generator to indicate electrode current in milliamperes passing through the two electrodes. This gives a direct indication of the ability of your water to conduct electricity at a safe level for highest quality, which is 1-2 milliamperes per square inch of electrode surface area.

3) Diluting:  Do not dilute the final Colloidal product with any kind of water.  We have discovered that mixing in unstructured water destroys the fine structure and Zeta Potential of the hexagonal structured colloidal water.

4) Electrode Mounting:       2 Extra outlets per channel allows an extra pair of electrodes to be mounted very close together to reduce the electrical resistance.  This allows more current to flow and to process distilled and other pure waters.

Our newly designed electrode mounting crossbar offers the added flexibility of extra electrode outlets which allows changing/controlling the distance between electrodes, when the distance is reduced more current will flow, when the distance between the electrodes is enlarged/widened less current will flow. This will aid in speeding up the process in low conductivity waters such as distilled and/or achieving the absolute highest quality Colloidal Silver (and other colloidal metal/mineral waters) by widening the distance to the maximum available. Your resulting current will be a function of the current control position on the generator, the type of water used, the distance between the electrodes and electrode area.

5) Productivity:  Much depends on the area of the electrodes. Our 2” x 6”  and   6” x 8” sheets of solid silver, gold, zinc,  magnesium etc will determine how much and how long the process will take, while still ensuring the highest quality. We cannot drive the metals with more than 1 to 2 milliamperes (mA) of current per square inch of electrode surface to ensure the smallest range of nanoparticle size, down to mono-atomic to pass the blood-brain barrier. Larger area allows larger current to safely provide faster, larger volumes. For example our 2” x 6”  domestic electrodes should be driven at 10 milliamperes to get 1 ppm per hour, whereas our 6” x 8” commercial electrodes can be safely driven at 50 mA to obtain 4 -5 times faster productivity.

Thanks for visiting and Happy Holidays.

Welcome to my Blog,

Electron Microscope Lab-Test Nanoparticle Size Confirmation.

Biophysica generated Colloidal Silver particle size is once again Laboratory confirmed to be the smallest in the business. In Colloidal Silver science smaller particle size is better, particles larger in size than 20nm  have much lower efficacy and may actually be harmful.

Colloidal Silver generated using small surface area as in wire or rods contains particles larger than 20 NM this is why we use large surface area electrodes. 

We recently sent a sample of our colloidal silver to a professional independent lab for size analysis (TEM).
The TEM report confirms that our nanoparticle size ranges from mono-atomic up to 10 nm.
Medical literature confirms that molecules larger than 20 nm cannot pass through the barriers that protect most organs especially the brain.
Here is the report with the Electron Microscope captured images.

The cheap, fast, dirty way to make colloidal silver.

By Dr John Stewart M.B., Ch.B., B.A. Sc.  5 August, 2018

INTRODUCTION: Most commercial Colloidal mineral waters, such as Colloidal Silver and Colloidal Gold,  are now  made by high voltage spark submerged under water because it is fast, efficient and low cost, because thin wires are used instead of the large area anode plates used by Biophysica, the leading professional electrolytic producer.  However a recent review of ESD Spark publications reveals that the resulting quality is significantly less than the gentle electrolysis method. Making nanoparticles smaller than 20 nm presents a formidable challenge that few can accomplish, but many claim.. Only an independent professional lab analysis can reveal the truth.


Historically in the preparation of nano-scale minerals, various chemicals were mixed to precipitate the small particles out of the solution. Now we have only two methods for the production of particles down to almost atomic size.
1) ESD.  In the ESD method, an electric arc is created with a very high voltage under water which melts the tips of the metal wires, exploding them into fine micro-particles having an average size of 100 nm (0.1 microns).
2) Electrolysis.  With our electrolysis method a pulsed DC voltage is applied between a  large area anode and cathode, made of the pure chosen metal.  Atoms are thus gently drawn off  from the anode (positive plate) and are swept into the bulk before being able to be deposited on the cathode (negative plate).


With this gentle method, independent lab results have confirmed that we obtain 1 part per million (ppm) per hour with a range of the finest nano-particles from 8 nanometers down to mono-atomic size and a very high  ZP of -60 millivolts.  PPM rises  to a saturation ceiling of 50 ppm where no more ZP charge can be carried.  Values of ppm reported by some manufacturers to be higher than 50 ppm, yellow or red color, would indicate that ZP is very low and particles are very large.  With slow, gentle  electrolysis method, the resulting colloidal water is clear and retains its potency for several years.  Many users buy their own Biophysica generator to make colloidal silver and other colloidal minerals at home at a fraction of the cost of commercially-sold liquid of dubious quality.

ZETA  POTENTIAL:  ZP is an electrical charge, well described in Wikipedia and is the measure of excellence of a colloid.  The molecular sized particles in a colloidal suspension carry an alkaline negative electrical charge (ZP) which is the most important particle characteristic because it determines many of the properties of the suspension. It is balanced by an opposite sign in the surrounding solution.  If the repulsion between approaching particles is large enough they will bounce away from one another and that will keep the particles in a state of suspension, up to the saturation maximum of 50 ppm.  If the ZP is too low (less than 20 millivolts), repulsive forces will not be strong enough, the particles will come together and may stick in a permanent diatom, then other particles may come along and also be caught in the growing aggregate. The suspension is then unstable and the aggregates will quickly settle out from the surrounding medium.  The ZP charges on the particle surface are normally attached to it very firmly as part of a structured hexagonal matrix and will remain there more or less indefinitely, even when diluted in the body of humans or animals, unless disturbed by mixing with unstructured water.  The higher the value of the zeta potential, the more stable the system will be. That means it will be better able to withstand additions of salt (which might otherwise destabilize it).

The two important measures of quality and efficacy of a colloid are nano-particle size and Zeta Potential (ZP).  Particle size made with the ESD method is larger, having an average size of around 100 nm and the smallest around 20-50 nm, far too large a range to pass the blood-organ barriers and therefore unable to combat infections in vital organs.  For example, the BloodBrain Barrier (BBB) is composed of a network of vessels that form a physical, electrostatic and chemical barrier between the brain and blood circulation. Most other organs have their own analogous protective barrier which can be easily damaged by a virus.  Diseases of the  retina, testis, ovary, prostate, kidney, liver, thymus, thyroid, placenta, pancreas are likely mostly caused by an invading virus which targets that specific organ then paves the way for subsequent bacterial growth. Even obesity is thought to be initiated by an adenovirus.
Large molecules, like chemotherapy drugs, antidepressants,  most antibiotics such as penicillin, do not pass through the BBB easily.  These barriers have evolved to prevent transport of bacteria, large molecules, and most small molecules bigger than 20 nm into the brain or organ.  Certain conditions such as mental stress, aging, viral or traumatic inflammation compromise the barrier increasing its permeability. Certain bacteria, although too large, can penetrate because of their rotating spiral structure (spirochaetes) which allows them to act like a power drill. These enter the brain and cause syphilis (Treponema), Lyme (Borrelia) and Leptospirosis.

Even with well maintained lab equipment the best ESD results fall outside of the desired effective range both for smallest particle size and for ZP.  Reported ESD best values for ZP is 30 millivolts (mv) instead of our 60 mv.  ZP  must be more than 30 mv to ensure stability of the nano-particles, otherwise particles agglomerate and fall to the bottom in a few days.

HEXAGONAL STRUCTURED WATER:  Structured water (SW) stores electron energy and has been shown to be antioxidant, more hydrating and can reverse certain biological markers of oxidative stress and aging,  SW water molecules join together in hexagonally structured single layer sheets which are flexible . All of the water in your body is structured water.  Energized structured water recharges the ATP battery of the body. When the body has sufficient energy, its aqueous interior is highly charged allowing for optimized cellular and metabolic function in addition to greater hydration and detoxification at a mitochondrial level.

QUANTUM EFFECTS:  Worthy of mention is the fact that when dimensions are less than 20 nm Quantum phenomena begin to become important. Such effects we might expect from our nanoparticles are:

  1. Tunneling through an unsurmountable barrier, such as bacterial membranes, biofilm.
  2. Non-locality or action at a distance by remote resonance.
  3. Bose-Einstein Condensate where all particles are in coherent alignment like a laser beam
  4. Wave-particle duality. An infinity of possibilities exist before the wave collapses.
  5. Observer Effect and interactions with Consciousness and the power of Intention on the hexagonal crystalline matrix.

COLLOIDAL GENERATORSBiophysica colloidal generators have largest area pure metal plates (up to 6 x 8 inches), constant controlled current, alternating reverse polarity, Mobius Coil, magnetic vortex using Neodymium magnet, high frequency pulsing (switching current on and off thousands of times per second)  as used in the electro-plating industry and  results in a very fine mono-atomic deposit.  The resulting mineral waters have hexagonal structure, highest bioavailability, nanometer size particles, colour is clear with no turbidity, highest total particle surface, highest Zeta Potential and potency against spirochetes, viruses, prions, yeasts, molds, fungus, algae which are more difficult to eliminate.

CONCLUSION   ESD and other techniques using thin wire or rod anodes make colloids of  borderline quality and although effective against some gram positive organisms are less effective against Gram negative bacteria like e coli, viruses and prions and are totally unable to enter the BBB because of their large size.  The pulsed low voltage electrolysis method used by Biophysica, when done slowly and gently, can provide a quality that far surpasses the ESD method.

Welcome to my Blog,


I just added a new video titled
Biophysica Colloidal Silver Generators, general overview may 2018 
Please click link to watch.

It gives the viewer a quick overview on our range of colloidal silver generators.
Biophysica produces the most advanced colloidal generators available. These generators not only produce the highest quality colloidal silver (lab tested and confirmed), they are also capable of producing a dozen other colloidal waters such as colloidal gold, colloidal magnesium and many more which the competition is simply not capable of.

Welcome to my Blog,

Question: What does Dr. Joel Wallach say about colloidal minerals?

Answer: Dr Joel Wallach believes colloidal minerals have special cosmic properties and a negative Zeta Potential charge that help the body process and absorb nutrients and vitamins from food sources and that these minerals have an anti-oxidant effect by releasing free electrons and also attract viruses, bacteria, toxins and heavy metals and flush them from the body. He claims these colloidal properties exceed the benefits of chemical compound formulations, more easily penetrate cell and mitochondrial membranes and blood-brain barrier and lead to improved health. All body fluids are colloidal.

Of the 60 minerals recommended by Dr Wallach, Biophysica sells 99.99% pure large area electrodes of silver, gold, magnesium, zinc, copper, platinum, palladium, tin, titanium, carbon, steel

New Electrode Sizes:   We can now obtain most of the popular metals in any size up to 8“x 8“ with purity of 99.99%.  We recently sourced  custom rolled large area Magnesium and Zinc which have been very difficult and costly to obtain with the 99.99% purity we demand (99.95% is readily available but is not pure enough).

Welcome to my Blog,

Concentration:  I prefer to use CS for ingesting and for topical use at a concentration of 48-50 ppm. Using a 2 gallon container and 2“x 6“ electrodes over 48 hours, I get 1 ppm per hour.  For the highest quality smallest almost monoatomic nanoparticles, turn the nanometer size knob to the lowest level.

Conversion table percent to ppm

Percent (%)



1 ppm


10 ppm


100 ppm


1000 ppm


10000 ppm

1 percent = 10000 ppm

One ppm is equivalent to 1 milligram per liter of water (mg/l) or 1 microgram per ml

1ppm = 0.0001% So to convert from ppm to percent, divide the ppm by 10000

Our 50 ppm colloidal silver contains 50 micrograms per ml, so that a minimal daily requirement of silver or copper would be 10 ml which = one third of an ounce = 2 teaspoonfulls

One tablespoonful = 0.5 ounces = 15 ml

Welcome to my Blog,

Dental infections can cause cancer and more. Only daily colloidal silver can penetrate deep inside the cells to protect us.  97% of all terminal cancer patients previously had a recent root canal procedure.  Root-canaled teeth are essentially “dead” teeth that can become silent incubators for highly toxic anaerobic bacteria that can make their way into your bloodstream to cause a number of serious medical conditions, many not appearing until decades later.  Many chronic degenerative diseases, including Alzheimer’s, originate from infected teeth and gums, the most frequent being heart, brain, joints and circulatory diseases.  16 different causative bacterial agents have been found for these conditions and most can cross the blood-brain barrier (BBB).  Most antibiotic molecules are too large (over 20 nm) to cross the BBB.  Highest quality small colloidal silver nanoparticles can.

Welcome to my Blog,

Electrodes:  We have now found a supplier for our electrode plugs, made of pure copper 2 mm (0.08 inches) diameter, plated with 24K gold for maximum signal transfer, durability, retention and resistance to corrosion. These are longer and will stay in the receptacle and not fallout easily. We solder each plug to a long copper stalk which is soldered to the electrode, then we insulate the assembly with food-grade epoxy. When inserting or removing our electrode from the generator, grasp the plug end (not electrode end) to pull or push in a straight line without bending which could break the plug or the epoxy. All of our electrodes are of 99.99% purity. We always stock electrodes of silver, gold, copper, zinc, magnesium, tin, iron, titanium, platinum, palladium, carbon, steel.

Silver protects against Alzheimer’s Disease:  More articles are appearing which connect Alzheimers with long-term bacterial or viral infections and genetic predisposition. Organisms responsible include Borrelia (Lyme), herpes, Chlamydia, all of which can be inactivated by Colloidal Silver. We all should be taking our minimal daily requirement of silver of 300 micrograms.  However CS quality is important. Nanoparticles of CS must be small enough (less than 20 nm)  to pass through the blood-brain barrier and have strong enough Zeta Potential to inactivate the vicious pico-viruses and prions (Mad Cow Disease). Our professional colloidal generators produce the highest Zeta Potential in our industry.
