Antimicrobial and Antibiofilm Biomaterials Strategies – RAPID FIRE

Timeslot: Wednesday, April 27, 2022 - 2:45pm to 3:45pm
Room: Harborside Ballroom A-B, 4th Floor


Treatment of microbial infections is complicated by rising antibiotic resistance and the inherent difficulty of treating biofilm-associated infections. In both scenarios, many current FDA approved antimicrobial drugs are ineffective, leading to a significant health and economic burden. Compounding these issues is a lack of development of new antimicrobial drug classes limiting the pipeline of available therapeutics. Advances in antimicrobial biomaterial therapies have the potential to improve outcomes for bacterial, fungal, viral, and biofilm-associated infections. Innovations in biomaterials are critically needed in the face of the COVID-19 pandemic, both for treatments of the SARS-CoV-2 virus, and also for effective treatment of the severe bacterial and fungal co-infections that have been reported. This session will cover biomaterials approaches to treat bacterial, fungal, and viral infections, including the prevention and eradication of biofilms. Strategies discussed may include antimicrobial surface modifications, device coatings, drug delivery, and immune engineering approaches.
