PCR rapid reaction chip

Abstract

The invention relates to a PCR rapid reaction chip. The PCR rapid reaction chip comprises a channel piece and a sealing fin closely attached to the channel piece. The channel piece is a thin film piece and comprises at least one PCR reaction group composed of a liquid adding hole, an exhaust hole and a PCR micro reaction pool communicated with the liquid adding hole and the exhaust hole. The liquid adding hole and the exhaust hole are formed in the surface of the channel piece. The liquid adding hole is communicated with the PCR micro reaction pool through a liquid adding channel. The exhausthole is communicated with the PCR micro reaction pool through an exhaust channel. One face of the channel piece is provided with a hollowed-out structure which forms the PCR micro reaction pool and isopened towards the sealing fin. One face of the sealing fin is closely combined with the face, with the hollowed-out structure, of the channel piece and covers the hollowed-out structure to form a PCR micro reaction pool cavity. The PCR micro reaction pool cavity, the liquid adding channel and the exhaust channel are connected to form an integrated cavity. The sealing fin is made of a metal filmor a biological film. Due to the structural settings, the PCR rapid reaction chip can be matched with a heating device, so rapid heating and cooling are realized, and the PCR reaction time is shortened.

Description

technical field [0001] The invention relates to the fields of biology and analytical chemistry, in particular to a PCR quick reaction chip. Background technique [0002] PCR (polymerase chain reaction) is an important means of molecular biology research, the reaction time has always been the limiting factor of PCR reaction, a conventional PCR reaction often takes one or two hours, in clinical testing, especially for emergency, so The long detection time limits its application field. With the development and application of PCR fast reagents, the bottleneck of reaction time is mainly concentrated on the heating and cooling speed. Based on this, how to improve the heating and cooling speed of PCR reaction has become the key to its expanded application. In addition, in the past, PCR testing equipment often started a new round of testing after the end of a round. In emergency applications, there are more and more demands for follow-up inspections, and the follow-up inspection fu...
