Colloidal Silver Generator

Construction of a Colloidal Silver generator with Arduino. The generator is programmed to produce 200mL of colloidal silver, with concentrations to choose between 10 and 100 ppm. Colloidal silver is composed of high-purity silver nanoparticles, which remain suspended in purified water. Silver nanoparticles measure between 5 and 100nm, and have a positive electrical charge due to the electrolysis process used in their production. Colloidal silver could be considered a homemade antibiotic, perhaps due to its lack of commercial interest from pharmaceutical companies.
