Abstract: The invention provides a microfluidic plate for various biological experiments and analyses. The microfluidic plate of the invention comprises one or more unit formed on or in the plate, wherein the unit comprises (a) a chamber; (b) a fluid channel adjacent to the chamber; (c) at least one microfluidic gap region connected between the chamber and the channel and in fluidic communication therewith; and (d) at least one opening located at the channel and connected with the gaps and in fluidic communication with the gaps.

Abstract: Disclosed is a micro-hole structure and a method for forming the micro-hole. A working energy source is projected onto a predetermined drilling site on a first surface of a substrate for a given period of time so as to melt a portion of the substrate to form a working energy entering section until the working energy source penetrates through a second surface of the substrate to form a micro-hole. A melt formed by melting a portion of the substrate in the micro-hole next to the second surface is allowed to reflow in a direction opposite to the projection of the working energy source to thereby form a reflow section in the substrate. Further, a two or more stages emission of laser pulses is used to form the micro-hole to control the bore diameter of the micro-hole.

Abstract: A cellular microarray is disclosed, which has a substrate, multiple first conductive lines, multiple second conductive lines, and multiple PIREs arranged on the surface of the substrate in an array. Each PIRE includes multiple first ring-shaped electrodes, and multiple second ring-shaped electrodes. The first ring-shaped electrodes, and the second ring-shaped electrodes are located on the surface of the substrate alternately in each PIRE. Moreover, the outermost ring-shaped electrodes of any two adjacent feather-shaped electrodes are different. The disclosed cellular microarray can adhere the cells rapidly and uniformly, increase the output of manufacturing, and reduce the cost for manufacturing and application.
