Keywords:Optical manipulation, black silicon, optical force

Toward optical manipulation of nanomaterials with high degree of freedom, we are challenging several research projects: (1) optical manipulation based on nanostructured solid surfaces, (2) optical manipulation at liquid/liquid interfaces, (3) selective optical manipulation based on resonant excitation, (4) application of optical manipulation for analytical chemistry. Here, the topic (1) is presented.
We call it NASSCA optical tweezers. Details have already been presented in :
