Published online: 10 September 2019
The electrophoretic mobility of a single nanoparticle depends on its surface charge and its environment. Thus the change of the mobility can reflect the change in its chemical and physical properties. We present a high-bandwidth method to measure the electrophoretic mobility, based on optical tweezers and electrophoresis. We envision studying of nanoscale chemical processes as a possible application of this method.
