A paper-based gene chip spotting method Kaipu Biology, Guangdong Kaipu Technology Zhi1 709179 Invention Patent China
Methods, devices, storage media and equipment Manufacturing Co., Ltd., Hanshan Normal University.6
As a high-throughput DNA analysis and detection method, gene chips are widely used in fields such as gene expression, disease diagnosis, and drug screening. The spotting process is a key step in gene chip experiments, which directly affects the signal intensity and data quality of the chip. Paper-based gene chips are gene chips made of paper-based materials. The characteristics of paper-based gene chips, such as uneven thickness and pore size differences, can easily limit the accuracy of spotting. The traditional solution is to deal with this problem by manually adjusting control parameters. However, this method highly relies on the operator's experience, and in most scenarios has problems with low spotting quality and low work efficiency. The invention's patent "a paper-based gene chip spotting method, device, storage medium and equipment" relates to the field of gene chip technology and provides a paper-based gene chip spotting method, device, storage medium and equipment. The method is applied to an inkjet-type spotting system. The inkjet-type spotting system obtains the information of the paper-based gene chip to be spotted from the manufacturing execution system. The target chip features are extracted from the incoming material quality control data, and the target chip features are input into the pre-trained parameter generation model. The parameter generation model predicts the best spotting parameters based on the chip characteristics, and then controls the inkjet print head to spot the paper-based gene chip based on the spotting parameters generated by the parameter generation model. Use AI technology to dynamically adjust spotting parameters based on chip characteristics to improve spotting quality, reduce the need for manual intervention, and improve work efficiency.
The company continues to move towards the goal of "leading nucleic acid molecular diagnostics company", continues to promote the "nucleic acid 99" strategy, promotes the continuous enrichment of the company's product structure, and meets the diversified needs of the market. The acquisition of the above-mentioned invention patent rights is in line with the company's development strategic plan and will not have a significant impact on the company's current operating conditions. However, it will help further improve the company's intellectual property system, give full play to the company's intellectual property advantages, enrich the company's product system, and enhance the company's core competitiveness.
Announcement is hereby made.
