Tiny particles called quantum dots reduce symptoms in mice primed to develop a type of Parkinson’s disease, and also block formation of the toxic protein clumps in Alzheimer’s. One day they could be a novel treatment for these brain disorders, although tests in people are some years away.
Quantum dots are just a few nanometres in size – so small they become subject to some of the strange effects of quantum physics. They have useful electronic and fluorescent properties and are found in some TV screens and LED lights.
Nanoco (LON:NANO) leads the world in the research, development and large-scale manufacture of heavy-metal free quantum dots and semiconductor nanoparticles for use in displays, lighting, solar energy and bio-imaging.
