A second electrical parameter which may be current, voltage or a combination of both is then adjusted and / or analyzed. Adjustments are carried out to facilitate analysis and / or obtain a desired degree of electroporation. Analysis is carried out to determine characteristics of the cell membrane and / or tissue.

The invention provides a pixel circuit that can cancel the influence of the mobility of a drive transistor. A drive transistor supplies to a light-emitting element, an output current dependent upon an input voltage during a certain emission period. The light-emitting element emits light with a luminance dependent upon a video signal in response to the output current supplied from the drive transistor. The pixel circuit includes a correction unit that corrects the input voltage held by a capacitive part before the emission period or at the beginning of the emission period, in order to cancel the dependence of the output current on the carrier mobility. The correction unit operates during part of a sampling period in response to control signals supplied from scan lines. Specifically, the correction unit extracts the output current from the drive transistor while the video signal is sampled, and negatively feeds back the output current to the capacitive part to thereby correct the input voltage.

Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in which electroporation and / or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought. Electroporation is achieved by applying a voltage between the two chambers, and diffusive transport is achieved either by a difference in solute concentration between the liquids surrounding the cell and the cell interior or by a differential in concentration between the two chambers themselves. Electric current and diffusive transport are restricted to a flow path that passes through the opening.

The system is also equipped to measure elapsed time and to stop fluid flow in response to either of the first and second output signals.
