Claim:
1. A pharmaceutical suspension comprising: a.) pharmaceutical grade water; b.) at least one processing enhancer comprising sodium bicarbonate; c.) gold nanocrystals suspended in said water forming a suspension, wherein said gold nanocrystals: i.) having surfaces that do not have organic chemical constituents adhered or attached to said surfaces; ii.) having a mode particle size of less than about 50 nm; iii.) are present in said suspension at a concentration of at least 2 ppm by weight per volume; and d.) said suspension having a pH of between about 5 to about 9.5, said gold nanocrystals having a zeta potential of about −20 mV or lower at a temperature of about 25° C., said zeta potential being determined by measuring the electrophoretic mobility of the gold nanocrystals in the suspension, and the suspension does not contain chloride ions.
