A Poly(acrylic acid)‐block‐Poly(L‐glutamic acid) Diblock Copolymer with Improved Cell Adhesion for Surface Modification

A novel PAA ‐b‐ PLGA diblock copolymer is synthesized and characterized that has excellent cell adhesion and biocompatibility. Fluorescent DiO labeling is used to monitor the attachment and growth of hASCs on the film surface, and cell proliferation over time is studied. Results show that PLLA modified by a CS/PAA ‐b‐ PLGA multilayer film can promote the attachment of human hASCs and provide an advantageous environment for their proliferation....
