Observation of Nanoscale Opto-Mechanical Molecular Damping; Origin of Spectroscopic Contrast in Photo Induced Force Microscopy

Mohammad A. Almajhadi, Syed Mohammad Ashab Uddin, H. Kumar Wickramasinghe

We experimentally investigated the contrast mechanism of infrared photoinduced force microscopy (PiFM) for recording vibrational resonances. Extensive experiments have demonstrated…

Detecting stimulated-Raman responses of few molecules using Optical Forces

Venkata Ananth Tamma, Lindsey M. Beecher, Jennifer S. Shumaker-Parry +1

We demonstrate the stimulated Raman near-field microscopy of few molecules, measured only using near-field optical forces thereby eliminating the need for far-field optical detecti…

Measurement of Laterally Induced Optical Forces at the Nanoscale

Fei Huang, Venkata Ananth Tamma, Hemanta Kumar Wickramasinghe

We demonstrate the measurement of laterally induced optical forces using an Atomic Force Microscope (AFM). The lateral electric field distribution between a gold coated AFM probe a…
