Optical Nanosensor Production Only Needs CDs, Tape, and Aluminum

Researchers at the Universidad Politécnica de Madrid (UPM) in Spain have developed a way to produce optical nanosensors that can stick to uneven surfaces as well as biological surfaces such as human skin. The researchers believe that this technique will expand the use of wearable devices for monitoring body temperature, respiration, blood pressure, and other vital signs. In research published in the journal Nanoscale , the Madrid-based team not only developed the fabrication technique to produce these optical nanosensors on regular adhesive tape, but also demonstrated a range of potential applications. Chemicals can be detected by the nanosensors because they change the film’s refractive index when they bind to it. The aluminum film along with the optical nanosensors also display iridescent colors. Because these colors can change according to the angle they are viewed it’s...
