🔬 A Biosensor That Glows by Itself..No Bulky Gear Needed! Scientists at EPFL (Switzerland), in collaboration with ICFO (Spain) and IBM Research, have developed the first-ever self-illuminating nanophotonic biosensor. It uses quantum tunneling to generate light inside the chip...removing the need for external light sources like lasers or LEDs. https://phys.org/news/2025-06-scientists-illuminating-biosensor.amp
