FERROUS PROTOPORPHYRIN WITH ENHANCED PHOTODYNAMIC ANTIBACTERIAL PROPERTY

Abstract

Public surface transmission is one of the most common methods of transmitting communicable diseases.The development of self-activating disinfectants is a novel idea. In this study, we have developed a photosensitizer that can be used as a photo-activated disinfectant. We have used Ferrous Protoporphyrin IX (FePPY9) which is a photosensitizer that can absorb visible light and shift to higher energy which will produce cytotoxic electrons and radicals when dropping back to a lower energy state.The enhanced antibacterial activity portrayed by FePPY9 is investigated using model organism, Escherichia coli, a Gram-negative bacteria.
