Background. Multi-drug resistant superbugs are a serious health threat due to limited treatment options and high mortality rates. Certain superbug strains are now resistant to as many as 36 representative FDA-approved antibiotics, including Colistin and Carbapenem antibiotics, widely considered as the last line of defense against untreatable infections. Nitric oxide (NO) is a diatomic free radi...

Self-healing hydrogel products have attracted a great deal of interest in wound healing due to their ability repair own structural damage. Herein, an all-natural self-healing based on methacrylated chitosan (CSMA) and dialdehyde bacterial cellulose (DABC) is developed. MA used modify CS obtain water-soluble biomaterial-based CSMA with photo crosslinking effects. BC modified through simple oxida...
