NuTek ODIO is the developer of Rainbow Probes, which can detect remaining cancer cells.

NuTek's Rainbow Probe is a tool used by the surgeon on a patient's body after removing the tumor mass.

It offers a real-time intraoperative scan and analysis of the operational cavity based on the tissue's bio-optical properties.

The Rainbow identifies residual cancerous tissue on the patient's body and guides the surgeon to its exact location for further removal.The first Rainbow application is breast cancer, aiming to drastically reduce repeated operations, to be followed by Rainbow versions for the liver and brain.NuTek won first prize at the 2020 Merage Institute 45+ Entrepreneurs' Competition.
