Fluorescent Dye Used to Identify Cancer Cells

Malignant tissue can often appear normal looking to the naked eye but this recently developed dye can light up cancer cells when fluorescent light is shined upon it during surgery.

Cytalux binds to cancer cells and has recently been given FDA approval. This enables the surgeon to be more accurate in removing cancerous cells. 

Developed by Dr. Phil Low from Purdue, this brief video explains the process. You can also read about this research by following this link.
