Background

The Hydrogel (Hydrogel) is a cross-linked polymer with a three-dimensional network structure formed by combining hydrophilic groups in a water-soluble polymer with water molecules to connect the water molecules inside the network and expanding the hydrophobic groups with water, has high water content and good biocompatibility, and is one of the most promising injectable biomaterials. Hydrogels can be classified as chemical hydrogels and physical hydrogels, depending on the bonding mode. Chemical hydrogel is three-dimensional network polymer formed by chemical bond crosslinking, and the hydrogel has stable properties, but the synthesis process is complex. The physical hydrogel is a polymer formed by non-covalent bond forces such as intermolecular hydrogen bond, static electricity, hydrophobicity and the like, is non-permanent, can show unique gel-sol phase transition behavior under slight change or stimulation of external environment, is simple in preparation process, does not introduce toxic reagents, and is poor in stability. Of course, there are many ways to classify hydrogels, such as natural polymer hydrogels and synthetic polymer hydrogels, depending on the synthetic materials. Here, we do not need to describe it again. In a plurality of drug carriers, the hydrogel has a high-hydrophilicity three-dimensional network structure which is beneficial to transporting oxygen, nutrient components and some water-soluble metabolites, and has the advantages of physicochemical property similar to that of a cell matrix, low interfacial energy, capability of reducing protein adsorption, easy degradability, non-inactivation of drug loading and the like. Thus, the hydrogel shows its own advantages in controlled release of the drug and in transportation. CN 105534878B-preparation of a double-responsiveness injectable supermolecule intelligent hydrogel; CN 102247602B-a supermolecular hydrogel dual drug carrier, and its preparation method and application, in the preparation of hydrogel, it needs many times of auxiliary processes such as precipitation, dissolution and precipitation.
