From an article at phys.org:
Dr. Gang Zheng and a team of biomedical researchers have discovered a “smart” organic, biodegradable nanoparticle that uses heat and light in a controlled manner to potentially target and ablate tumours with greater precision.
The proof-of-concept findings, published online today and designated a “very important paper” in the leading chemistry journal Angewandte Chemie, provide a viable approach to boosting the clinical utility of photo-thermal therapy in treating cancer, says Dr. Zheng, Senior Scientist at the Princess Margaret and Professor of Medical Biophysics at the University of Toronto. Dr. Zheng also holds the Joey and Toby Tanenbaum/Brazilian Ball Chair in Prostate Cancer Research.
