Below you will find the two main reasons to purchase a Biophysica built Colloidal Silver Generator.

Please read through the reports below to introduce yourself to the two defining features of Biophyca technology, size and current. When done please proceed to visit the rest of the site for an introduction and in-depth look at Colloidal Silver, its production and its benefits.

Biophysica built generators are the most versatile in the business they are capable of producing a dozen other colloidal minerals and metals such as Colloidal Gold, Colloidal Magnesium and many more. Thanks for visiting.

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.

Lab-test Zeta Potential Confirmation

It is becoming apparent that even the most up-to-date analytic laboratories and equipment manufacturers are using equipment that is sufficiently obsolete as to be unable to reliably detect or measure nanoparticles less than 100 nanometers. This challenge becomes even more difficult when the colloidal samples we send are too dilute, less than 50 parts per million (mg/litre), and we want information down to 1 nm in size. Because the sample concentration is too low, there may not be enough light scattered to make a measurement.

Tunable Resistive Pulse Sensing (TRPS) measures nanoparticles suspended in electrolytes on a particle-by-particle basis as they pass through a nanopore. According to IZON, the manufacturer, this is a huge step forward as the more commonly used light scattering techniques only provide bulk estimates with low accuracy and very low precision. TRPS has the unique ability to accurately measure the zeta potential of individual nanoparticles. This is incredibly important when working with samples that are polydisperse in size or charge

The precision, resolution, and accuracy of size measurement in TRPS is unmatched by any other nanoparticle analysis technique. The transient current pulse caused by a particle traversing the pore is directly proportional to particle volume, enabling a highly precise and repeatable measurement of size to be achieved; in ideal conditions TRPS offers sub nm resolution of diameter. Every particle measured is compared to a set of NIST traceable calibration particles of known size, which ensures accuracy and repeatability. This calibration step enables the real size distribution of a particle set to be generated to a very high precision and accuracy. The measurement of particle concentration is also the best available, with data accuracy on a linear scale. By way of comparison, Dynamic Light Scattering (DLS) such as Malvern Zetasizer is unable to measure concentration at all, and NTA is only accurate on a log scale and is too coarse for most scientific purposes. Traditionally the nanomedicine field has relied on DLS measurement, sometimes backed up by TEM. DLS is now an inappropriate and obsolete technology especially for sizes smaller than 50 nm.
