Hyaluronic acid (HA) microgels modification with polyethylene imine (PEI) is accomplished. P(HA)-PEI possess strong antibacterial effects against E. coli, S. aureus, and B. subtilis. P(HA)-PEI microgels are biocompatible for L929 fibroblast cells. P(HA)-PEI particles can inhibit MDA-MB-231 breast, and H1299 cancer cells growth.
