CHARACTERISTICS OF HIGH STRUCTURE POLYMER HYDROGEL FOR USE FOR BIOMEDICAL PURPOSES

Abstract

Currently, in highly technologically developed countries, polymer hydrogels capable of reversibly swelling tens and hundreds of times in water and biological fluids are widely used in various fields of medicine. Polymer hydrogels, which are hydrophilic polymers interconnected in space, have a unique set of valuable physical, chemical and medical-biological properties (tunable sorption capacity for a wide range of water and biological fluids, biocompatibility, soft tissue-like consistency, permeability to large and small molecules, non-toxicity, etc.). This determines the high efficiency of their practical application in many areas of medicine, such as internal and intra-tissue prostheses (plastic surgery of soft tissues, cartilage, tendons, etc.), contact lenses for vision correction, hemocompatible materials, fundamentally new tools for the treatment of wounds and burn lesions of the skin, systems of controlled release substances and means of direct delivery of various drugs to the organ, etc.
