Dr. John Stewart Blog – 10

Welcome to my Blog,

We know that Colloidal Silver effectiveness is very dependent on the electrical charge on each nanoparticle, called Zeta Potential.  Recent colloidal research from King Abdullah University of Science and Technology (KAUST) is revealing how nanoparticles work as catalysts to inactivate viruses and bacteria. We at Biophysica for several years have included high frequency waveforms in our technology to produce a range of the smallest nanoparticles down to mono-atomic size in order to combat the most vicious small viruses which cause brain damage.  However, it now appears that this range must include slightly larger particles carrying a specific optimal number of atoms unique to each colloidal mineral, which for silver is 25. According to KAUST “Nanoparticles with an atomically precise number of constituent atoms have properties based on the particular number of atoms of each individual nanoparticle with unique energetic states and catalytic properties. These atomically precise nanoclusters are the key to understanding catalysis. This allows the clusters to remain in an energetically excited state for a long time whereby the electrons of the metal atoms are shared across the entire cluster, having unique optical and electronic properties”.  KAUST also found that surrounding silver nanoclusters with negatively charged hydrogen-rich shells offers new opportunities in catalysis and opto-electronics.  “Simple organic citrate ions, derived from readily available citric acid, can interact with and stabilize colloidal gold nanoparticles to yield the stable nanoparticles needed as powerful catalysts and anti-cancer agents”.  The unique healing properties of combination of Silver and Gold, called Electrum by ancient alchemists, may be explained.  “Altering a single atom in a silver nanocluster considerably changes its properties, creating an exciting opportunity to design these clusters. Replacing a single atom in a cluster of 25 silver atoms with one gold atom fundamentally changes its properties”.
