A New Proof of Concept in Bacterial Reduction: Antimicrobial Action of Violet-Blue Light (405 nm) in Ex Vivo Stored Plasma

Figure 1

Inactivation of bacterial contamination: (a) S. aureus, (b) S. epidermidis, and (c) E. coli, in phosphate buffered saline (PBS) rabbit plasma and human plasma by exposure to 405 nm light with irradiance of approximately 100 mWcm⁻² (n = 3 ± SD). Nonexposed control samples for all experiments demonstrated no significant change in population over the exposure period [].
