This Feature Application shows the huge potential that Nanolive imaging holds for the drug discovery process, where cytotoxicity remains one of the major causes of drug withdrawal, and there is an urgent need for reliable and time-saving assay workflows. Our first case study features an in-depth investigation of the dynamics of cell death following exposure to seven cell death stimuli: extreme shifts in external pH, thermal stress, phototoxicity, oxidative stress, Shikonin, Ebastine, and Taxol. Our second case study shows that we can quantify drug-dependent and dose-dependent effects in 96-well plate format.
