Real-time Measurement of the Single Nanoparticle Electrophoretic Mobility

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 tweeze...

Description
Summary:	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.
