Fardian-Melamed et al. showed that force can do the same. The authors used an atomic force microscope (AFM) to apply force to a doped sodium yttrium fluoride nanocrystal, and measured the ...

Researchers at the Columbia University School of Engineering and Applied Science have invented ‘all-optical’ nanoscale sensors of force that change intensity or color when you push or pull on ...

Two independent teams in the US have demonstrated the potential of using the optical properties of nanocrystals to create ...

A tactile sensor based on an optical fibre ring resonator helps blind or partially sighted people interact seamlessly with ...
