Antibiotic resistance of pathogenic microbes in healthcare and community settings is a quickly growing and extremely dangerous health threat. There is consequently a critical need for the development of alternative therapeutics. The mission of Dai lab is to develop light-based nonpharmacological approaches to counteract the increasing emergence of antibiotic-resistant infections.
Antimicrobial blue light: Antimicrobial blue light (aBL), a novel light-based approach, has attracted increasing attention due to its intrinsic antimicrobial effect without the involvement of exogenous photosensitizers. The mechanism of action of aBL is still not fully understood. A common hypothesis is that aBL excites naturally occurring endogenous PS (iron-free porphyrins or/and flavins) within microbial cells and subsequently leads to the production of cytotoxic oxidative species.
Antimicrobial photodynamic therapy: Antimicrobial photodynamic therapy (aPDT) uses a combination of non-toxic photosensitizers (PSs) together with harmless visible light. Originally developed as a tumor therapy some of its most successful applications are for non-malignant disease such as localized infections.
