DOI: 10.1007/s10965-017-1431-0
Abstract: A novel pH-responsive Fe3O4/poly(2-succinyloxyethylmethacrylate-co-methylmethacrylate) (poly(SEMA-co-MMA)) nanocomposite was designed for anticancer drug delivery applications. For this propose, poly(2-hydroxyethyl methacrylate-co-methylmethacrylate) (poly(HEMA-co-MMA)) was synthesized via reversible addition-fragmentation transfer (RAFT) method. Then, poly(SEMA-co-MMA) was prepared by the esterification of… read more here.
