The invention relates to a quaternary ammonium salt derivative containing benzimidazolic acid hydroxypropyl trimethyl chitosan, and a preparation method and application thereof
The invention belongs to the technical field of nano biomedicine, and particularly relates to a quaternary ammonium salt derivative containing benzimidazolic acid hydroxypropyl trimethyl chitosan as well as preparation and application thereof. Using benzimidazolic acid hydroxypropyl trimethyl chitosan quaternary ammonium salt, carboxymethyl chitosan, sodium hyaluronate and sodium alginate as raw materials, the target product containing benzimidazolic acid hydroxypropyl trimethyl chitosan quaternary ammonium salt nanogel, the average particle size of the product is 255.61 nm-331. 48 nm, and the Zeta potential is +32.72-+37.94 mV. The nanogel containing benzimidazolic acid hydroxypropyl trimethyl chitosan quaternary ammonium salt prepared by the invention can be used for entrapping antitumor drugs, shows pH responsive release behavior, and is a carrier with good application value.
