Sub-micromolar imaging of intrinsic chromophores by two-photon photothermal microscopy captures mitochondrial response to chemotherapy
Nathaniel Hai, Chinmayee Vallabh Prabhu Dessai, Dingcheng Sun +4
Intracellular chromophores (e.g., NADH and FAD) play a central role in regulation of cellular metabolism. Though autofluorescence has been extensively used for label-free mapping o…

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…
