Abstract Purpose To study the targeting and photodynamic therapy efficiency of porphyrin and galactosyl conjugated micelles based on amphiphilic copolymer galactosyl and mono- aminoporphyrin (APP) incoporated poly (2-aminoethyl methacrylate)-polycaprolactone (Gal- APP-PAEMA-PCL). Methods Poly (2-aminoethyl methacrylate)-polycaprolactone (PAEMA- PCL) was synthesized by the combination of ring opening polymerization and reversible ...
