Medical masks proved effective in protecting against the virus during the Covid-19 pandemic. However, conventional masks are poorly biodegradable. For this reason, the presented paper produced environmentally friendly chitosan/silver/plant fiber membranes for masks, which also exhibited antibacterial and thermal properties.

Deeper skin injuries require appropriate wound dressings to promote healing. In the presented study, CMC-containing hyaluronic acid-dopamine hydrogels were synthesized, characterized and investigated in vivo for their wound healing properties.
