Research on Fully Automated Nucleic Acid Extraction Microsystem and Detection Based on Voice Control
To solve the problem of high efficiency and precision nucleic acid extraction in microscale environment,an automatic nucleic acid extraction microsystem was proposed in this study. The system integrates nucleic acid extraction chip,air channel,pressure,and vacuum tube,and realizes automatic flow operation of sample solution,washing solution,and eluent through integrated control of microcontroller. Through the control of a smartphone app,users can easily implement the fully automated process of extracting nucleic acids from biological samples,effectively avoiding human interference and significantly reducing the risk of exposure to infection. To verify the success of nucleic acid extraction,diphenylamine reagent was used for preliminary color change detection to quickly determine whether nucleic acid was successfully extracted,and the extraction effect was further verified by solid-state nanopore sensing experiment and nucleic acid sequencing technology to ensure the accuracy and reliability of the extraction results. The experimental results show that the automatic nucleic acid extraction microsystem is not only easy to operate,but also has high efficiency and accuracy.
