Amrita Center for Nanosciences and Molecular Medicine scientists Dr. Shantikumar V. Nair and Dr. Manzoor Koyakutty invent a technology that enables cancer detection in less than 30 minutes without a hospital visit. This will enable early diagnosis and treatment that are vital for curing several forms of the disease. The technology uses a laser with a nano substrate to detect pre-cancerous and cancerous cells.
