The present invention relates to a method for the preparation of concentrated colloidal dispersions of silver nanoparticles obtained using various water-soluble polyoxyalkylated derivatives of calixaranes of the general formula (1), the values of the substituents being given in the description serving as an effective colloid-stabilizing additive . Stabilized colloidal dispersions of silver nanoparticles are used in human and veterinary medicine, pharmacy, cosmetics, nanotechnology and electronics, for the production of antiseptic and antibiotic drugs, etc. |
