A bortezomib-chitosan complex was synthesized based on the esterification reaction between bortezomib peptide boronic acid and hydroxyl groups of chitosan;the carbon quantum dot enters the chitosan system through the electrostatic adsorption of the chitosan amino of bortezomib-chitosan complex and carboxyl of carbon quantum dot's surface to get bortezomibchitosan-carbon composite quantum dot nanoparticle carrier.This product has the nature of biocompatibility,non-toxic side effects,fluorescent tracer and pH...
