Observations of x-ray radiation pressure force on individual gold nanocrystals

摘要

We report observations of x-ray radiation pressure force on individual single nanocrystals using an x-ray single molecular methodology. The observed gold nanocrystals are linked to the adsorbed protein molecules. We observed the directed Brownian motion of individual linked nanocrystals. The observed force is estimated at about 0.13-0.63 aN. We will be able to control and measure dynamics of micro- or nanocrystalline materials using x-ray radiation pressure force.
