Schematic diagram of MPDA drug delivery system to improve the healing effect of RL-QN15. AÂ Successful preparation of nanocomposites of MPDA and RL-QN15. BÂ MPDA released RL-QN15 on the surface of wound. CÂ RL-QN15 induced the cytokines secretion from macrophages. DÂ The migration and proliferation of keratinocytes and fibroblasts induced by RL-QN15. EÂ The wounds treated with nanocomposites of RL-QN15 healed completely
