Researchers from the University of Technology Sydney (UTS) have deployed the existing principles of optical tweezer technology, which enables the manipulation and assemblage of nanoparticles, as a base for a technique that allows them to manipulate particles possessing the same refractive properties as those of the background environment in a given setting. Optical tweezing relies on a difference in the refractive properties between trapped nanoparticles and the surrounding environment. The new method, shown as a proof of concept, involves doping nanocrystals with rare-earth metal ions...Read full articleRelated content from Photonics MediaARTICLESChirality and Nanotechnology Speed Up Light-Based Drug ScreeningA team of international collaborators has introduced a drug-screening technique that relies on nanostructure chirality as its fundamental property.
