A high school student from Calgary has won the Sanofi BioGENEius Challenge Canada competition for his research into an experimental cancer therapy.
Arjun Nair, 16, is a grade 11 student at Webber Academy. His winning experiment involved photothermal therapy (PTT), which is used to treat cancer.
With PTT, a patient is injected with gold nanoparticles. A nanoparticle is a microscopic particle of a substance, less than one-millionth the size of a grain of sand.
The gold nanoparticles collect in the patient’s cancerous tumours. When the tumours are bathed with laser light, the nanoparticles heat up and kill the cancer cells.
