METHOD OF OBTAINING SUPRAMOLECULAR HYDROGEL Russian patent published in 2018 - IPC A61K9/00 A61L2/16 A61P31/00 B82B1/00 

FIELD: chemistry.

SUBSTANCE: method of obtaining supramolecular hydrogels includes mixing an aqueous solution of L-cysteine with the silver acetate aqueous solution so that the concentration of L-cysteine in the mixture is in the range of 1.0 to 6.0 mmol, and the ratio of molar concentrations of silver acetate to L-cysteine in the mixture is in the range of 1.23 to 1.33, where the mixture is left in a dark place at room temperature for 4 hours for the formation of the L-cysteine-silver solution. Then, the mature L-cysteine-silver solution is mixed with an aqueous solution of sulfate with a cation from the series Na⁺, K⁺, Cu²⁺, Fe²⁺, Mg²⁺, Zn²⁺, Al³⁺, Ni²⁺, Co²⁺, Mn²⁺ at a concentration of sulfate in the mixture in the range of 0.075-0.750 mmol, after a certain time, depending on the concentration of sulphate and the type of cation, after which the liquid system becomes a gel.

EFFECT: improved method.
