Imaging rotational dynamics of nanoparticles in liquid by 4D electron microscopy
Abstract
Advances in microscopy techniques aim to make it possible to study materials under more realistic conditions, such as in liquid cells, or to use fast probes to capture dynamics. Fu et al. combined liquid cell transmission electron microscopy with ultrafast pump-probe spectroscopy to perform time-resolved studies of nanoscale objects (see the Perspective by Baum). They successfully captured the change in rotational dynamics of coupled gold nanoparticles and also observed the dynamics as two particles fused together in a liquid environment.
