Researchers from the Institute of Materials Science in Juazeiro, Brazil have reported on the antibacterial properties of usnic acid, a strong lichen metabolite, encapsulated in electrospun fibers. The team’s work was published in Recent Patents on Nanotechnology.
Usnic acid has been used in commercial products, such as creams, toothpastes and sunscreen, due to their antiviral, animicrobial and anti-inflammatory properties. To optimize the use of this compound as an alternative to antibiotics, the team of researchers sought to identify a way to encapsulate the compound and release it in a controlled manner at varying levels of acid concentration.
