Abstract—The antimicrobial photodynamic activity of protoporphyrine IX (PPIX) in conjunction with red light - emitting diode (LED) and xenon lamp was carried out against Staphylococcus aureus (S.aureus). At 30min illumination using the red LED and 30μM of PPIX 99.8% reduction of S.aureus survival was achieved. Based on optofluorometric study, it is further observed that the measurement of steady-state native fluorescence of amino acid, tryptophan provided a method to monitor the Antimicrobial photodynamic therapy (APDT) efficiency by optical means.

Index Terms—Antimicrobial photodynamic therapy, red LED, protoporphyrine IX.
