Synthesis, Characterization And Properties Of Chitosan-Poly (Methacrylic Acid-Co-N-Isopropylacrylamide) Hydrogel For Drug Delivery

The application of chitosan has received enormous attention in medical field particularly in drug delivery. In this study, chitosan with two monomers, methacrylic acid (MAA) and N-isopropylacrylamide (NIPAM) were prepared by emulsion polymerization to form a chitosan-poly(methacrylic acid-co-N-isopr...
