Abstract

The invention provides a polymethylmethacrylate material micro-fluidic chip processing technology which is a technology used for processing of a micro-fluidic chip apparatus, belonging to the technical field of instrumental analysis science. A micro-fluidic chip is an apparatus used for rapid detection and analysis of liquid substances. The technology in the invention is a low-cost rapid processing technology for the micro-fluidic chip. The technology comprises direct laser printing of the micro-fluidic chip, heat sealing, hot-melt embedding and fixing of electrodes and circuits of the chip, designing of electric signal transmission through communication between the micro-fluidic chip and external equipment in virtue of contact electrodes and designing of a removable micro-fluidic chip fixing mount. With the technology provided by the invention, production of a micro-fluidic chip not involving an organic solvent is cheap, and the micro-fluidic chip is convenient to use and even becomes a disposable consumable. If the polymethylmethacrylate material micro-fluidic chip processing technology is used in batch production, cost for micro-fluidic chips is lower, and a critical promotion effect is exerted on industrialization and popularization of the micro-fluidic chips.

Description

technical field [0001] Microfluidics Chip or Lab-on-a-chip technology belongs to the frontier field of analytical testing science and is used for rapid and accurate analysis of biology, medicine, chemistry, food and water quality. It is one of the most advanced and hot technologies in the field of analytical science today. [0002] In life sciences, the lab-on-a-chip technology dominated by microfluidic chip technology has gained some significant applications. Using this technology can realize the monitoring and early diagnosis of multiple diseases for multiple patients on a small chip at the same time.
