Fluorescence Lifetime Microscopy (FLIM) of intrinsic biomarkers has demonstrated an exceptional capability to non-invasively investigate the energetic and metabolic redox state of living tissues at the cellular level.
We develop novel approaches for fast Fluorescence Lifetime Microscopy and novel label-free optical methods for metabolic imaging in stem cells and living tissues.
