Physics World Nanotechnology Briefing 2021

In this free-to-read Physics World Nanotechnology Briefing we showcase the breadth of applications of modern nanotechnology. We talk to researchers developing nanoparticles designed to cross the blood–brain barrier to image and destroy brain cancer cells. And we speak to a company helping to supply nanoparticles in the quantities required for aviation, healthcare and energy.
Also in this briefing we investigate a new type of quasiparticle discovered in graphene, which could be used to create high-speed transistors. And we look at nanotechnology being used on the supermarket shelf – where carbon nanotubes are being used to detect ethylene, which is involved in the ripening of fruit and vegetables; and quantum dots have been developed that emit light when fish spoil and emit a potentially dangerous compound. Energy production and storage is another burgeoning area of nanotechnology: researchers have developed an energy-harvesting device made from graphene, and have created diamond-like carbon nanothreads, which can store large amounts of energy when twisted.
