What makes American Biotech Labs process so unique as to warrant a new patent? As was stated above, ABL has determined what the optimum size, volume, configuration, electrical charge and harmonic range for silver particles should be to produce the best and most effective silver product. Let’s take each of these attributes one at a time. OPTIMUM SIZE: The crucial difference between a silver solution that will inhibit the growth of bacteria by using a massive dose of 1500 to 300,000 ppm ; and a silver solution that can kill the same bacteria by using a concentration of only 2.5-5.0 ppm – is dependant upon the scientifically arrived at optimum size and form of silver particles and a newly developed process that can create optimum nano particles that have many times more beneficial results than just mixing silver with water.
