Stimulation/control system for TFT array biosensor — Application to dielectrophoresis
2018
We present a system with waveform generator with 28×2 modular outputs for the control of Thin-Film-Transistors array devices used for biological applications. The generator has a range of amplitudes as large as −5V to +27V, and allows application of arbitrary shapes of electrical signals, including DC, AC, pulses and else. Thin-Film-Transistor array devices are very new and promising transparent substrates with integrated microelectrode array for very local biological experiments on a whole array. The generator allows the individual control of the microelectrodes in a very flexible way permitting various biological application. Demonstration of micro-beads manipulation using dielectrophoresis technique is presented.
