To detect cancer at early stage is critical for treatment. In order to spot tumors before they become too big to cure, researchers at Massachusetts Institute of Technology (MIT) developed an optical imaging system using near-infrared light to spot tiny tumors. The MIT research team noted that near-infrared light with wavelengths from 900 to 1700 nanometers, is suitable to tissue imaging because light with longer wavelengths does not scatter as much as when it strikes objects, allowing the light to penetrate deeper into the tissue. Using the advantage of near-infrared light, r...

Technology has realized many stories we learnt from sci-fi fictions and movies. A new technology like the “dermal regenerator” in Star Trek that heals wound with laser was developed by a research team from Arizona State University. Kaushal Rege, professor of Chemical Engineering at Arizona State University, and his team members has published a paper on Advanced Functional Materials which describes how they successfully repaired animal wounds with laser-activated silk and gold nanomaterials. The researchers embedded gold nanorods in a silk protein matrix as...
