PM2.5, due to its small particle size, strong activity, ease of the attachment of toxic substances and long residence time in the atmosphere, has a great impact on human health and daily production.

Therapeutic drugs remain of great significance for the absorption of wound blood, the closure of wounds and rapid wound healing. Hence, we propose a novel composite nanofiber membrane with the above characteristics as a wound healing material. We utilize the reaction of calcium ion and alginate gel, sodium alginate (SA) and Rana chensinensis skin peptides (RCSPs) extracted from discarded Rana chensinensis skin; these two natural substances were successfully used to prepare composite nanofibers by coaxial electrospinning.
