Quick response detection device based on silicon-based microstructure

Abstract

The utility model relates to a quick response detection device based on a silicon-based microstructure, which comprises a reaction device main body and an end cover, the end cover is covered on the reaction device main body, the middle part of the reaction device main body sinks to form a sinking groove, and the space between the sinking groove and the end cover is used for accommodating the silicon-based microstructure. A liquid drop flow channel and a reaction cavity are formed in the positions, located on the two sides of the sinking groove, of the reaction device body in the long axis direction and communicate with the two sides of the sinking groove correspondingly, a liquid dropping opening and a through hole are formed in the end cover, and a fluid flow channel communicating with the liquid drop flow channel and the reaction cavity is formed in the silicon-based microstructure. A fluid to be detected is placed into the liquid drop flow channel through the liquid dropping opening and enters the reaction cavity through the fluid flow channel for reaction. According to the rapid response detection device based on the silicon-based microstructure, the continuous wedge-shaped grooves are formed in the fluid flow channel to imitate the microstructure characteristics of common nepenthes to form a capillary phenomenon, so that the effect of automatically conveying fluid is achieved, and the conveying efficiency of the fluid is further improved.
