Abstract

Photodynamic therapy is a technique for killing cells with visible light after pretreatment with a photosensitizing agent. We demonstrated significant in vitro fungicidal activity against Aspergillus fumigatus of the photosensitizer Green 2W, activated with 630 nm light. This effect was both inoculum- and light dose-dependent. At a Green 2W concentration of 31.5 mg/L, there was complete killing of 2.7 × 10¹ cfu/mL with a light dose of 110 J/cm² and up to 2.7 × 10⁶ cfu/mL with a light dose of 385 J/cm².
