If a worker wants to do something good, he must first sharpen his tools. In today's globalization, patents are not only a means of protection for innovation, but have become a weapon in the commercial battlefield. Mames Consulting has created a patent operation platform for MEMS, sensors and IoT, integrated intellectual property resources in the entire industry chain, and actively promoted the protection and effective use of intellectual property. At present, the interaction between cells and substrates has attracted great attention in the biological and chemical world. For biosensing, implantable biomaterials, and tissue engineering, how to control cell adhesion in specific areas is an urgent problem to solve. Surface structures with nano-roughness (such as nanoneedles, nanoprotrusions, and nanopores) have adhesion to cells. These nanostructures can be achieved through a series of methods, including nanoimprinting, electron beam nanolithography, and injection molding. .
Current MEMS-based cell microarray chips are widely valued by researchers. Micro-scale graphic structures are constructed on the substrate by micromachining technology, and the surface is modified by physicochemical modification to enable selective adhesion of cells in specific regions, thereby forming an ordered cell microarray. Biological and genomic libraries for cell differentiation, transfection, and intercellular communication can be performed on cell microarray chips by controlling the culture environment or specific design of the adhesion region to analyze changes in cell growth behavior and related components. Medical research such as screening and drug screening. Combined with fluorescence analysis and computational image processing technology, the two-dimensional planar cell array chip has the advantages of convenient focusing, high-throughput screening and fast data processing, which improves the experimental efficiency. At the same time, the miniaturization of the experimental platform is realized, and the reduction is effectively reduced. Research costs. [Recommended invention patent] "Microwave array based on MEMS technology and its manufacturing method" [Invention content] In order to overcome the shortcomings of traditional experimental analysis methods such as biological drug screening, which require a large number of samples and cannot be analyzed in real time, The invention provides a method for preparing a cell microarray structure based on a MEMS process, the main steps of the method comprising: spin-coating a photoresist on a surface of a silicon substrate, photolithography and developing to form a patterned array structure; using a DRIE etching process Silicon micro/nano wires are formed on the silicon substrate; thermal oxidation is performed to form a silicon oxide layer.
The invention discloses a cell microarray trough type (left) and a column (right) structure. The invention adopts the mature MEMS technology to realize simple and rapid preparation of different microarray structures. After the microarray structure is completed, the dicing is obtained. The size of the microarray chip, the microarray chip is placed in the cell culture medium for cell adhesion culture, the cells will automatically adhere to the treated super-hydrophilic nano-silica region, and finally the designed fixed-point controllable cell micro- Array structure.
