Embodiment Construction

[0037] The drug detection test paper of the invention is based on the principle of fluorescence immunoassay, and can quantitatively measure the drug content in saliva. The structure of the test paper is as figure 1As shown, the test paper substrate 1 is made of polyethylene terephthalate. The test paper includes a detection area 2 and a sampling area 3, and the detection area 2 and the sampling area 3 are connected. The array of micro cylinders 4 distributed in the detection area 2 and the sampling area 3 constitutes the microfluidic capillary structure of the test paper.

[0038] like figure 2 As shown, the height of each micro cylinder 4 in the microfluidic capillary structure is 30 microns, the diameter is 30 microns, the interval between adjacent micro cylinders is 30 microns, and a hydrophilic layer 7 is covered on the surface of each micro cylinder.

[0039] The saliva collector drips the collected saliva sample into the sampling area 3 , and the saliva sample is uni...

Abstract

The invention discloses narcotic detection paper based on a microfluid capillary structure and a preparing method thereof. The narcotic detection paper is based on the fluorescence immunoassay principle, and the narcotic content in human body saliva can be accurately and quantitatively measured. The s narcotic detection paper is of the microfluid capillary structure, the problems that traditional fluorescence immunoassay detection paper is high in background fluorescence, and saliva samples are difficult to evenly diffuse are solved, and the advantages that the fluorescence immunoassay technology is high in sensitivity, and quantitative analysis can be carried out are fully developed. Shaping of the microfluid capillary structure of the narcotic detection paper is carried out with the reel-to-reel heat photoetching technology; by means of the method, the preparing cost can be greatly reduced, the preparing period is shortened, and large-scale production of the narcotic detection paper is achieved.

Description

technical field [0001] The invention relates to a drug detection test paper, in particular to a drug detection test paper based on a microfluidic capillary structure and a preparation method thereof. Background technique [0002] In recent years, drug abuse has gradually penetrated into people's daily life, such as driving after taking drugs, taking drugs in entertainment venues, etc. With the improvement of the legal system and the enhancement of citizens' awareness of protecting their own rights and interests, in the process of drug testing, it may be difficult for law enforcement officers to collect blood and urine samples on the spot. Other samples that are easier to obtain are needed to replace them, and saliva is one of them. one. Saliva samples offer the following advantages over urine and blood samples: [0003] 1. The collection process of saliva avoids the violation of the privacy of the subject; [0004] 2. No need for special collection equipment; [0005] 3....
