“…A few biopolyelectrolytes are listed here dextran sulfate, carboxymethyl cellulose, hyaluronic acid, chitosan, poly- l -lysine, protamine, gelatin A, and so on . Our group has utilized natural biopolymers for designing novel LbL multilayer capsules for specific applications in targeted drug delivery, , gene delivery, , antimicrobial drug delivery, controlled drug delivery using pH-responsive drug release, intracellular-enzyme-responsive drug release, ,,− magnetic-force-controlled drug release, or microshock-wave-triggered drug release . Some of the results are discussed here.…”
