[Comparative study of the effect of the metals Ag, Cu, Zn and Al in the form of a highly dispersed powder and salt on Escherichia coli B. growth]
Izv Akad Nauk SSSR Biol. 1983 Nov-Dec;(6):948-50.

The comparative study of the antimicrobial activity of the finely dispersed Ag, Cu, Zn, Al salts and suspension was carried out. Only the powders of metals, which were active in ionic form (Ag, Cu, Zn) show the ability to inhibit the growth of E. coli. The toxicity series for Ag+ > Cu2+ > Zn2+ > Al3+ ions was changed under transfer to finely dispersed powders in such a manner, that Ag and Cu were interchanged the position.
