Singlet oxygen destroys pathogenic bacteria 🦠
The concept of antimicrobial photodynamic HELBO therapy (aPDT) is based on the staining of the bacterial membrane by light-sensitive dye molecules of a photosensitizer that diffuse into the biofilm.
The dye molecules are then activated by laser light and transfer their energy to local oxygen. This creates highly aggressive singlet oxygen, which significantly destroys bacteria, even in the biofilm.
Such effectiveness is unimaginable with conventional treatment methods.
