Abstract In this study, a unique rapid processing technology for microfluidic chips made of polymethylmethacrylate (PMMA) was realized. The common laser engraving machine is used to etch the chip reaction unit and microchannel, and the printing chip is what you see is what you get; the pressurized heat sealing technology is used to quickly complete the chip sealing and packaging; the metal electrodes and lines that need to be laid are embedded into the chip by hot melting; the contact points on the fixed base of the contact chip card are used to connect with the external equipment, so as to make the bearing sample react, detect and complex lines and chips. It is self-contained and isolated from the external equipment circuit. The chip becomes disposable and can be replaced quickly and conveniently. The chip processed by this technology has rapid, cheap and convenient improvement and innovation, which makes the production of microfluidic chip easier and more practical, and even makes the chip a disposable consumable with general interface, which will greatly promote the industrialization of microfluidic chip, and has market-oriented promotion value in the field of water quality and food detection.
