Electrophoretic mobility is the rate of movement of a molecule or particle to an electrode in response to an applied electric field. Laser Doppler electrophoresis is commonly used to measure electrophoretic mobility. However, contact of the protein with the electrodes required for the application of the electric field is known to damage proteins and can cause them to denature and aggregate [3]....
Electric fields have been employed to promote macromolecular crystallization for several decades. Although crystals grown in electric fields seem to present higher diffraction quality, these methods are not widespread. For most configurations, electrodes are in direct contact with the protein solution. Here, we propose a configuration that can be easily extended to standard crystallization meth...
When a carbon nanotube emitter is operated at high currents (typically above 1 microA per emitter), a small voltage drop ( approximately few volts) along its length or at its contact generates a reverse/canceling electric field that causes a saturation-like deviation from the classical Fowler-Nordheim behavior with respect to the applied electric field. We present a correction to the Fowler-Nor...
