In situ semi-quantitative assessment of single-cell viability by resonance Raman spectroscopy
Currently, studies are increasingly focusing on the cytotoxic effects of anticancer drugs. Such investigations urgently warrant the assessment of single-cell viability. Here, we developed a novel method for quantifying single-cell viability with high selectivity by resonance Raman scattering. We report on this powerful tool that will allow researchers to study cellular metabolism at the level of a single cell.
