The emergence of multi-drug-resistant pathogens threatens the healthcare systems world-wide. Recent advances in phototherapy (PT) approaches mediated by photo-antimicrobials (PAMs) provide new opportunities for current serious antibiotic resistance. During PT treatment, reactive oxygen species or heat produced PAMs would react with cell membrane, consequently leaking cytoplasm components and effectively eradicating different like bacteria, fungi, viruses, even parasites. This Perspective...
