Multimolecular Super Resolution Metabolic Imaging in Aging and Diseases
Embedded Files
We developed a super resolution (~59 nm) multimolecular SRS metabolic imaging platform. Integrating it with Fluorescence Lifetime Imaging (FLIM), multiphoton fluorescence (MPF), and second harmonic generation (SHG), we achieved a multimodal imaging system.

We discovered lipid-, protein-, carbohydrate-, and DNA/RNA-specific Raman shifts, and developed spectral unmixing methods to achieve macromolecular selectivity at subcellular resolution.
