LEDs made from food waste; New DNA technology has big potential

LEDs made from food waste
University of Utah researchers have found a way to create LEDs (light emitting diodes) from food and beverage waste. LEDs can be produced by using quantum dots (QDs), or tiny crystals that have luminescent properties, to produce light. They can also be made from carbon dots (CDs), which are simply QDs made of carbon. Compared to other types of quantum dots, CDs have lower toxicity and better biocompatibility, enabling their use in a broader range of applications.
