Abstract:
In this study, we present confocal Raman microscopy for chemically selective analysis of a human buccal epithelial cell layer with a focus on label-free visualization of particle uptake into the cells. We demonstrate the suitability and benefit of this analytical technique in comparison to confocal fluorescence microscopy for three dimensional imaging of in vitro cell models.
