Nano‐Optical Tweezers: Methods and Applications for Trapping Single Molecules and Nanoparticles

Abstract Optical tweezers were developed in 1970 by Arthur Ashkin as a tool for the manipulation of micron‐sized particles. Ashkin's original design was then adapted variety purposes, such trapping and biological materials [1] laser cooling atoms. [2,3] More recent development has led to nano‐optical tweezers, particles on scale only few nanometers, holographic which allow dynamic control multiple traps real‐time. These alternatives conventional optical have made it possible trap single molecules perform studies them. Presented here is review developments their current future applications.
