Rutgers university is developing a new medical imaging method that uses rare earths nanocrystals an infrared light. The method aims to detect cancer and similar diseases at earlier stages, allowing for faster and less intensive treatment.

As quoted in the publication:

The Rutgers technology, co-developed by Richard Riman, distinguished professor of Materials Science and Engineering, uses a different type of infrared light than is used for imaging today. Called shortwave infrared, it penetrates skin and other tissue more deeply than visible light or the near-infrared light used in current imaging methods. This light stimulates dyes made with nanocrystals of rare earth elements – a family of 17 similar metals that are not scarce but are difficult to mine. Rare earths are in growing demand for electronic products such as smart phones, video screens and electric car motors and batteries.

While scientists and physicians have long recognized the potential value of shortwave infrared light, fluorescent dyes that react to this light have either been too toxic to use safely or could not deliver sharp images. The dyes that Moghe and his team are developing encapsulate rare-earth nanocrystals in a shell of human serum albumin. They are well tolerated, distribute quickly through the body and accumulate at the disease sites.
