Imaging the Hopping of Small Particles in Liquid Cells Containing Water

What is it about?

Here, we studied how gold nanocubes in water move within the liquid cells that used for TEM imaging at 100 frames per second acquisition rate. We find that the nanocubes move with a mix of short shuffles and intermittent long jumps.

Why is it important?

This paper attempts to reconcile the mechanisms behinds suppressed motion of nanoparticles within the liquid cells used for TEM. We propose that our results can explained using desorption-mediated motion on a non-uniformly charged surface, which we attributed to the different surface-termination of silicon nitride.
