Test strip for detecting amphetamine and preparation method and application of test strip

Abstract

The invention discloses a test strip for detecting amphetamine and a preparation method and application of the test strip. The test strip comprises a sample absorption pad, a conjugate release pad, areaction membrane, a water absorption pad and a substrate in sequence, wherein an antibody which is marked by time resolution fluorescent microspheres is sprayed to the conjugate release pad; a detection line of hapten-carrier protein conjugate and a quality control line of a sheep anti-rat secondary antibody are coated on the reaction membrane. By adopting the test strip, the antibody is marked by the time resolution fluorescent microspheres, immunochromatography assay is adopted, and rapid immunoassay of amphetamine can be achieved. The invention further provides a method for detecting amphetamine in a sample by using the test strip. The test strip has the advantages of being high in sensitivity, accurate in quantification, rapid in detection, convenient to operate and economic and practical, and rapid detection and on-site detection on large-scale amphetamine samples can be achieved.

Description

technical field [0001] The invention relates to the detection of amphetamine, in particular to a test strip for quantitative detection of amphetamine by using time-resolved fluorescent microsphere immunochromatography technology and a preparation method and an application method thereof. Background technique [0002] Amphetamine, or amphetamine, is the prototype of a series of synthetic drugs with pronounced stimulant effects on the central nervous system. It is classified as a drug because of the addictive nature of intravenous injection. Adverse reactions caused by amphetamine include symptoms such as excessive excitement, restlessness, insomnia, tremor, tension and irritability. Physical tolerance to amphetamines develops very quickly, so long-term users must take more and more. The most severe consequence of high doses of amphetamines is a toxic neurosis with symptoms resembling paranoid schizophrenia. Abuse of amphetamines often occurs together with abuse of barbitur...
