摘要： An automatic injection device comprises at least an injection unit (1). The said injection unit (1) is formed by sealing a cover plate layer (3) with hydrophilic surfaces and a microfluid layer (4). The said cover plate layer (3) is provided with at least two through holes (5). The said microfluid layer (4) is provided with a hollow-out hybridization chamber (7) and at least two hollow-out microfluid channels (6). One end of each channel (6) is connected with the hybridization chamber (7), and the other end is connected with a through hole (5) of the cover plate layer (3) respectively. Taking advantage of the hydrophilicity of the cover plate, the automatic injection device makes a solution automatically enter and fill the hybridization chamber (7) and the microfluid channels (6) by the driving force of liquid surface tension. The flow uniformity of sample solution in microarray chip is achieved by the structural design of the hybridization chamber (7) and the microfluid channels (6). The automatic injection device has advantages of simple manufacture, easy operation, high hybridization efficiency, low sample cost, and automatic quantificational injection.

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.
