    摘要: A microelectrode sensing device includes a substrate and an array of microelectrode sensors. Each sensor includes a first conductive layer that at least partially conducts electricity. The first conductive layer is formed above the substrate and patterned to include a recording electrode that measures electrical activities of target cells. Each sensor also includes a second conductive layer that at least partially conducts electricity. The second conductive layer is elevated above the first layer and patterned to include multiple positioning electrodes arranged to define a sensing region above the recording electrode. The positioning electrodes are designed to generate an electric field pattern in the sensing region to move and confine the target cells to a sub-region of the sensing region that at least partially overlaps the recording electrode.

    摘要: A method and apparatus for washing solid substrate with ultrasonic wave after hybridization reaction are provided. The method includes (1) putting the solid substrate into a container having a washing solution, on which the hybridization reaction has been completed, (2) using an ultrasonic generator to produce a certain strength of ultrasonic wave and transmit it into the washing solution, (3) washing the substrate by means of the cavitation effect being produced in the washing solution by the ultrasonic wave. Since the cavitation bubbles in the washing solution can produce intensive efflux and local microslipstream against the solid surface, evidently reducing the liquid surface tension and friction and enhance the liquid flow, non-specific adsorbate and deposit bound weakly on the solid substrate can be washed down rapidly.

    摘要: A micro fluidic device comprises one microstructure layer (5) and one cover layer (1), wherein the cover layer (1) is connected to the microstructure layer (5). The microstructure layer (5) comprises one bottom layer and a plurality of microstructures on it to position samples. The cover layer (1) comprises one top layer, one positioning well (6) and at least one inlet pool (4). The positioning well (6) is right above the microstructures and connected with each other. The inlet pools (4) and the positioning well (6) are connected by microchannels (3) which are formed between the microstructure layer (5) and the cover layer (1). The micro fluidic device can be applied in vitro fertilization, in determining how glial cells affect neurons, in constructing neural network and in detecting cell growth conditions.
