Monitoring Excited-State Relaxation in a Molecular Marker in live cells – a Case Study on Astaxanthin
in: Chemical Communications (2021)
Small molecules are frequently used as dyes, labels and markers to visualize and probe biophysical processes within cells. However, very little is generally known about the light-driven excited-state reactivity of such systems when placed in cells. Here an experimental approach to study ps time-resolved excited state dynamics of a benchmark molecular marker, astaxanthin, in live human cells is introduced.
