  • POLY-ION COMPLEX MICELLE
    Publication number: 20240075148
    Abstract: A poly-ion complex micelle comprising: a block copolymer having a hydrophilic block portion, a cationic hydrophobic block portion and a crosslinking block portion positioned between the hydrophilic block and the cationic hydrophobic block, and an anionic molecule drug encapsulated by the block copolymer, wherein the crosslinking block has a hydrazone bond, the block copolymer comprises the first block copolymer chain and the second block copolymer chain, the first block copolymer chain and the second block copolymer chain crosslinked to each other in the crosslinking block portion, the hydrophilic block portion comprises the first hydrophilic block of the first block copolymer chain and the second hydrophilic block of the second block copolymer chain, and the cationic hydrophobic block portion comprises the first cationic hydrophobic block of the first block copolymer chain.
