As antibiotic resistance continues to rise at an alarming pace, the global medical community is urgently searching for alternative ways to combat infectious diseases. One powerful contender stepping into the spotlight is photodynamic therapy (PDT)—a light-based technology once limited to cancer treatment and dermatology. Now, this innovative therapy is breaking new ground in infection control, offering a targeted, non-invasive, and drug-free approach to neutralize pathogens, even those resistant to conventional antibiotics.
Photodynamic therapy harnesses the power of light-activated molecules to generate reactive oxygen species (ROS) that destroy bacteria, viruses, fungi, and biofilms without harming healthy tissue. As antibiotic-resistant superbugs threaten public health worldwide, PDT offers a new paradigm in microbial management—precise, scalable, and less prone to resistance. This article explores how PDT works, its expanding applications in infection control, and why it may soon become a frontline tool in the post-antibiotic era.
