    摘要: Microtechnologically prepared component as a flow cytometer. The component contains a preparation area to specifically influence and separate the particles, preferably by dielectrophoresis, a measuring channel area for characterizing the particles, and a sorting area for sorting the particles identified in the measuring channel area by dielectrophoresis. The sorting includes switching elements which permit active guidance of the particles into two or more subchannels corresponding to the criteria which have been registered in the measuring channel area. With a component configured in this way for the use of a flow cytometer, quick and precise sorting of particles, in particular biological cells in a suspension, can be implemented.

    摘要: A method for discrimination of particles, preferably biological cells, in a measurement channel having a liquid for transporting the particles by impedance spectroscopy. Pairs of measurement and reference electrodes are arranged in the measurement channel. During movement of a particle through the pair of measurement electrodes, the pairs of measurement and reference electrodes are admitted with same input signals having different frequencies. Measurement values at the measurement and reference electrodes are compared to determine particle specific values for the particle being moved through the measurement channel. The particle specific values for the different frequencies are normalized to a particle specific basic value at a basic frequency; and then the normalized particle specific values are compared with corresponding values of at least one reference particle at the same different frequencies. The comparison shows changes in the capacitance or in the conductance of the particle, which are used in discriminating the particle.

    摘要: An over-current protection circuit including, a current supply switch with a first terminal coupled to a supply current input and with a second terminal coupled to a supply current output. The current supply switch is switchable at least between an on-state, in which the current supply switch provides a conductive connection between the first terminal and the second terminal, and an off-state, in which the current supply switch interrupts the conductive connection between the first terminal and the second terminal. The over-current protection circuit receives a supply current via the supply current input and provides the supply current via the supply current output if the switch is in the on-state. The current supply switch includes a High Electron Mobility Transistor.

The device includes multiple microelectrode elements arranged along an elongated probe shaft. The microelectrode elements are dimensioned and shaped so as to target individual neurons, groups of neurons, and neural tissue as may be located in an animal nervous system, such as deep within a human brain. Beneficially, the neurological probe can be used to facilitate location of the neurological target and remain implanted for long-term monitoring and/or stimulation.
