"sample stained with photoswitchable Raman probes, whose Raman scattering controlled by different kinds laser... illuminate sample and build image of it... irradiated with 2-color IR laser pulses for detecting Raman scattering, UV and donut-shaped visible light, constrains Raman scattering area... final stage imaging detects probe, leads to a high spatial resolution... adding more colors to Raman probes, RESORT image many components in living samples... high power or precise control. biological samples"
