Abstract
An embodiment of the present disclosure discloses a microfluidic detection device, the microfluidic detection device includes: a first substrate configured to include a first surface and a second surface opposite to each other, a light source is provided on the first surface, and a light source is provided on the second surface. At least one grating block is arranged on it; the second substrate is configured to include an opposite third surface and a fourth surface, and at least one photosensitive detector is arranged on the third surface of the second substrate facing the first surface; the microfluidic channel Layer, which is arranged between the first surface of the first substrate and the third surface of the second substrate, the microfluidic channel layer includes microfluidic channels for microfluidic circulation; at least one grating block reflects the light emitted by the light source, each The collimated light rays of corresponding colors reflected by the grating blocks are transmitted through the microfluidic channel and received by the at least one photosensitive detector. The microfluid detection system of the embodiment of the present disclosure has a simple structure, low processing difficulty, low cost, high spectral separation precision, high detection and recognition precision, and low crosstalk.
Description
technical field [0001] The present disclosure relates to the field of detection instruments, in particular to a microfluid detection device. Background technique [0002] Instruments that detect tiny objects have been a subject of long-term research by scientists. Among them, the spectrometer, as an analytical instrument, is widely used in various scientific fields, especially in the research of physics, chemistry and biology, etc. It is one of the most important observation methods. Stained cells or substances are detected or collected. [0003] However, the current miniaturized spectrometers such as miniature quantum dot spectrometers have complex structures and complicated preparation methods. Contents of the invention [0004] The technical problem to be solved in the present disclosure is to provide a microfluid detection device with simple structure and low processing difficulty. [0005] In order to solve the above technical problems, an embodiment of the present...
