Abstract

Raman spectroscopy using non-invasive near-infrared (NIR) laser light has become a powerful tool for the microscopic analysis of organic and biological materials. A Raman tweezers microscope (RTM) was developed by combining NIR Raman spectroscopy with the laser trapping technique, which enables us to expand the scope of single particle studies. Recent results obtained using the RTM for single droplets and polymer spheres in a micrometer range are reported.
