Holographic Optical Tweezers


Researchers from #unicomplutense report in Optica how to create freestyle laser traps that can confine single and multiple microparticles in a large variety of 3-D curved shapes such as spirals, knots, waved rings and polygons. 

Their versatility and easy control of optical forces open up new perspectives for study of particle dynamics and design of light driven micromotors. This optical technology has also potential applications in optofluidics, laser micromachining and microbiology. ow.ly/SfEpl
