active in small quantities or at low concentrations.

Silver is the preferred antimicrobial agent, but its relatively high cost prompts researchers to explore the oligodynamic effect of other heavy metals such as copper and zinc.
The silver ions were described as "oligodynamic" owing to their higher bactericidal competency at minute concentrations [48].
9,771,549 B2; Conopco, Inc., Englewood Cliffs, NJ, has patented a cleansing composition that contains a surfactant (soap); an oligodynamic metal selected from the group consisting of silver, oxide, silver nitrate, silver acetate, silver sulfate, silver benzoate, silver salicylate, silver carbonate, silver citrate or silver phosphate; and a chelating agent.
In contrast, in the precedent studies conducted on bacterial resistance to silver in wound care [67, 68] revealed that the [Ag.sup.+] show oligodynamic effect with minimum development of resistant microorganisms.
Olarte explained that silver is an oligodynamic metal, whose metal ions kill and inhibit the growth of fungi, bacteria and other microbes.

The oligodynamic effect of metals on biological systems (including the antimicrobial properties) was already described in 1893 by Nageli (Nageli 1893).
Silver has been described as being "oligodynamic" because of its ability to exert a bactericidal effect on products containing silver, principally due to its antimicrobial activities and low toxicity to human cells [26-29].
The oligodynamic property of silver ions binding to both microbial DNA preventing bacterial replication and to sulfhydryl groups of metabolic enzymes of bacterial electron transport chain, causing their inactivation [12] is responsible for its broad spectrum antimicrobial activity.
The recognition of the anti-microbial activity of oligodynamic metals such as silver has been a basis for the development of many anti-microbial processes and products.
