It is a useful therapy with several drawbacks that limit its effectiveness, including prolonged light sensitivity, poor tissue penetration and off-target toxicity. These drawbacks can prevent complete ...

Researchers have developed light-sensitive chemicals that can eliminate tumors in vivo in mouse models of breast cancer with minimal side effects. | Drug Discovery And Development ...

Antimicrobial photodynamic therapy (aPDT) consists of the administration of a photosensitizer combined with a light source at a specific wavelength, and oxygen. The procedure generates reactive ...

A ground-breaking cancer treatment using new light-sensitive chemicals has demonstrated remarkable success in eliminating aggressive breast cancer tumours in mice, paving the way for safer and more ...

"This approach could prove to be an effective way to treat many cancers, and holds great promise because of the limited risks and side effects associated with photodynamic therapy, or PDT," said Dr.

Interestingly, this form of light therapy is already used in photodynamic therapy in which low-level red lasers activate drugs injected into a site of infection. Photodynamic therapy is primarily used ...
