Article in ACS Photonics

Kelvin Zhu, Ken and Wuzhou Song are authors on a paper published in ACS Photonics today, Direct Particle Tracking Observation and Brownian Dynamics Simulations of a Single Nanoparticle Optically Trapped by a Plasmonic Nanoaperture. The article describes simulations that were performed to gain insight into optical trapping by nanostructures that were combined with stochastic Brownian diffusion to determine particle trajectories. This research will be a valuable tool for the better understanding of fundamental mechanisms underlying nanostructure-based trapping
