Scientists have unveiled a groundbreaking antibiotic technology that activates only when exposed to green light—offering pinpoint precision in treating infections and reducing the risk of antimicrobial resistance (AMR).
This innovation uses “caged” antibiotics that remain dormant until triggered by light, allowing them to kill bacteria exactly where needed—be it in wounds, on implants, or beneath the skin.
In lab and early animal trials, this targeted method doubled survival rates, showed remarkable effectiveness against E. coli and S. epidermidis, and even disrupted stubborn, antibiotic-resistant biofilms.
To supercharge the effect, researchers are combining this method with light-sensitive nanomaterials and natural photosensitizers like curcumin and flavonoids—making it a powerful weapon against deadly superbugs such as MRSA and A. baumannii.
This new approach brings fresh hope in the fight against drug-resistant bacteria, promising more targeted treatment and fewer side effects.
🧪 In the near future, we could see wearable light patches or fiber-optic implants treating infections deep within the body.
