FIELD: colloidal chemistry, chemical technology.
SUBSTANCE: method involves mixing cysteine aqueous solution with silver nitrate aqueous solution to provide final concentrations of cysteine from 1 x 10-3 M to 6 x 10-2 M and that of silver nitrate from 3 x 10-3 M to 1 x 10-1 M in a mixture, and this mixture is remained in thermostat at temperature 10-40°C for 15-24 h. Invention provides preparing gel used as a carrier for peptides and proteins that possesses biocide properties and without their changes after two years storage at room temperature.
EFFECT: improved preparing method.
