Glowing quantum dots made from mango leaves

Glowing quantum dots made from mango leaves

By heating dried mango leaf extract, researchers have synthesized fluorescent graphene quantum dots that can be used for bioimaging and as intracellular temperature-sensing probes1. Existing fluorescent materials, such as organic dyes, metal clusters and quantum dots, are toxic to biological cells and unstable when exposed to light. In search of a biocompatible fluorescent material, scientistsRead more about Glowing quantum dots made from mango leaves[…]

Smarter routers and processors for better communication systems

A team of physicists has developed a new way to control the paths of light beams trapped in liquid crystals using laser beams and external magnetic fields1. This magneto-optical control will aid in developing efficient and robust signal processing methods for optical communication systems. “Our method can replace some important elements in the optical communicationRead more about Smarter routers and processors for better communication systems[…]
