The forms of silver (Ag) utilized from B.C.E until present day, having sizes ranging from visible to the naked eye (1 mm and above) to approximately 0.1 nm (atomic radius and above) [35,37,38,39,40]. Various pathogens within each category (e.g., the Toxocara canis [usually 2–10 cm] and the pinworm Enterobius vermicularis [usually 1–3 mm] for macro pathogens >> 1 mm) depict a size comparison for the Ag forms [41,42,43,44]. Comparative scales are approximated.
