Abstract(s)[Excerpt] Wound infections are generally caused by pathogens and multidrug-resistant (MDR) strains that render the administration of antibiotics ineffective. An alternative is to treat infected wounds at the initial stage using a fibrous bionanopolymer, bacterial nanocellulose (BNC), functionalized with antimicrobial metal nanoparticles (MNPs). BNC is a highly promising wound dressing due to its very high-water retention capacity (> 99 %) and high porosity. Such properties enable the absorbance of exudates, whilst maintaining the environment moist allowing the exchange of air. However, BNC is absent of antibacterial properties, thus gold (Au), copper (Cu), and copper oxide (Cu2O) NPs were incorporated within the nanofibrous structure of the biopolymer via in situ synthesis.
