Mechanisms of microbial photoinactivation by curcumins micellar delivery

Highlights • Microbial photoinactivation efficacy is higher when curcumin-Surfynol 465 micelles are used. • Surfynol 465 may disrupt the cell’s membrane, enhancing inactivation. • Non-partitioned curcumin may have a significant role in microbial photoinactivation. 1 Introduction Microbial photodynamic inactivation (PDI) has received considerable attention as a novel strategy for surface sanitation that could potentially replace the currently used methods. PDI uses photosensitizers (PS) in...
