Label-free Imaging of Single-Biomolecule Structure and Interaction by Stimulated Raman Photothermal Encoded Scattering
Pin-Tian Lyu, Yifan Zhu, Qing Xia +8
Current single molecule methods either rely on fluorescence or lack chemical information. Here we report stimulated Raman photothermal encoded scattering (SRPSCAT) microscopy for q…

Micromolar chemical imaging by high-energy low-photodamage Coherent Anti-stokes Raman Scattering (HELP-CARS)
Guangrui Ding, Dingcheng Sun, Yifan Zhu +5
Coherent anti-Stokes Raman scattering (CARS) microscopy offers label-free chemical imaging capabilities, but its performance is constrained by small Raman scattering cross-section,…

Fiber laser based stimulated Raman photothermal microscopy with long working distance optics
Xiaowei Ge, Yifan Zhu, Dingcheng Sun +4
Stimulated Raman scattering (SRS) microscopy is a highly sensitive chemical imaging technique. However, the broader application of SRS has been limited by two key challenges: the r…
