Porous forming jig for polydimethylsiloxane micro-fluidic chip

Abstract

The invention provides a porous forming jig for a polydimethylsiloxane micro-fluidic chip. The porous forming jig for a polydimethylsiloxane micro-fluidic chip comprises an upper die, a lower die is arranged at the bottom of the upper die, the upper die and the lower die are connected through a plurality of connecting rods, a plurality of gaskets are arranged between the upper die and the lower die, a die groove is formed in the top of the lower die, an air hole needle is arranged in the die groove, a male die is arranged at the bottom of the upper die, the bottom of the upper die is sunken inwards to form a groove, the male die is located in the groove, the top of the lower die protrudes upwards, the die groove is formed in the protrusion, and the outer edge of the protrusion is connected with the inner wall of the groove in a sealed mode. The polydimethylsiloxane micro-fluidic chip porous forming jig provided by the invention has the advantages that: the use is convenient, one-time forming can be realized, cutting is not needed, meanwhile, the hole opening precision is high, deviation is avoided, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a polydimethylsiloxane microfluidic chip porous forming jig. Background technique [0002] Microfluidic chip technology refers to the science and technology involved in systems that use micropipes to process or manipulate tiny fluids, and is an emerging interdisciplinary subject involving chemistry, fluid physics, microelectronics, new materials, biology, and biomedical engineering . Because of the characteristics of miniaturization and integration, microfluidic devices are usually called microfluidic chips, also known as lab-on-a-chip and micro-full analysis systems. Microfluidic chips are mostly produced by polydimethylsiloxane. . [0003] Polydimethylsiloxane, referred to as PDMS, is a hydrophobic silicone material. Making microfluidic chips with PDMS materials has the advantages of easy processing, low cost, etc., and has good chemical inertness and biocompatibility. ...
