Thermally Limited Force Microscopy on Optically Trapped Single Metallic Nanoparticles

Year: 2019

Type: article

Abstract: Measuring optical forces at the nanoscale with optimal resolution of both position and force is crucial in optical-trapping physics. This study presents a method to measure radiation pressure on metallic nanoparticles down to the thermal limit, with a large dynamic range and fine resolution in position. This progress is made possible by a careful assessment of the conditions of stability through an Allan-based deviation analysis. The capacity to measure femtonewton forces is important in the context of optical spin-orbit interactions and chiral forces.
