- Nanoparticle formulation of a chlorophyll-rich biomolecular extract of an Indian medicinal plant Anthocephalus cadamba (Kadamba Tree) combined with a near-infrared dye has been found to selectively kill skin cancer cells.
- The plant extract is toxic to cancer cells as there is enhanced generation of reactive oxygen species (ROS) while the dye aids in the destruction of cancer cells through Photo Thermal Therapy.
- On being irradiated with near-infrared light, the dye gets heated up and facilitates the release of the extract from polymer membrane. After 4-5 minutes of irradiation, about 80% of cancer cells were killed
- Two teams from Indian Institute of Technology (IIT) Hyderabad and IIT Bombay working together have achieved promising results using skin cancer
- Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation for the treatment of various medical conditions, including cancer.
