Photodynamic Action of LED-Activated Curcumin against Staphylococcus aureus Involving Intracellular ROS Increase and Membrane Damage
Figure 3
Membrane permeability of S. aureus was measured using flow cytometry with PI staining after LED light-activated curcumin (2.5 μM, 3 J/cm2). (a) Sham control; (b) curcumin treatment alone; (c) blue light irradiation alone; (d) blue light-activated curcumin.
