Abstract

The invention relates to a microfluid structure, in particular relates to a microfluid array device, and solves the problems that the conventional microfluid structure for biological detection is not beneficial to extraction of micro detection signals and can easily damage detected cells. The microfluid array device comprises a microfluid array layer, a coverage layer bonded on the upper surface of the microfluid array layer, and a substrate layer attached and fixed at the lower surface of the microfluid array layer, wherein two columns of microfluid structure units, and two longitudinal microfluid straight channels parallel with each other are respectively formed on the upper surface of the microfluid array layer; one column of microfluid structure units comprises the same number of microfluid structure units (which are linearly arranged at equal intervals) as that of the other column of microfluid structure units; and each microfluid structure unit comprises a micro reaction cavity and a transverse microfluid straight channel communicated with the micro reaction cavity. The microfluid array device is suitable for the fields of cell detection, cell cultivation, medicine screening, medicine transportation and the like.

Description

technical field [0001] The invention relates to a microfluidic structure, in particular to a microfluidic array device. Background technique [0002] Microfluidic technology is currently a research hotspot in the field of MEMS, which mainly includes cell detection, cell culture, drug screening, drug delivery, etc., and is usually widely used in bioengineering, environmental monitoring, food engineering, clinical medicine and other fields. Biosensors are an important tool for studying various life phenomena at the molecular level. They have the advantages of high specificity and high sensitivity, but they also have disadvantages such as weak output signals and poor anti-interference ability. As an essential key technology for the integration and miniaturization of biosensors, microfluidic technology can enhance the output signal of biosensors and improve the anti-interference ability of biosensors. Therefore, biosensors developed based on microfluidic technology (ie, microfl...
