Essentials of MPM-spectral-FLIM skin imaging. (a) Emission spectra for main endogenous fluorophores in the skin and for nano zinc oxide. (Redrawn with permission from Ref. 8.) (b) Skin imaging using the DermaInspect^® system in the Therapeutics Research Center at University of Queensland (UQ). (c) Typical high-resolution image of viable epidermal cells after acriflavine treatment with the DermaInspect^®, color-coded to visualize mean fluorescence lifetime, ${\tau }_{\mathit{m}}$. Scale bar is $40\mu \mathrm{m}$. (d) Schematic of detectors in the DermaInspect^® based at UQ.
