Abstract

The invention discloses a preparation method and application of a multi-metal oxygen cluster functionalized cadmium sulfide nanowire sensor array. Due to multi-metal oxygen cluster modification, the specific recognition enrichment capability of a material upon a drug can be improved, the detection sensitivity of a single photoelectric sensor can be improved, and the response time can be shortened;due to construction of the sensor array, the cross sensitivity of the sensor array upon different types of drugs can be improved; due to adoption of the project, a nano photoelectric gas-sensitive sensor array is established according to expect, the response discrimination degree of a sensation element upon drugs of similar structures can be increased, non-contact recognition detection on commondrugs such as opium, heroin, amphetamin chloride, ketamine and cocaine can be achieved, and a base of sensitive material can be made for a portable drug detector. The sensor array can be applied to accurate and non-contact detection on hidden trace drugs.

Description

technical field [0001] The invention belongs to the technical field of chemistry and relates to a preparation method and application of a non-contact drug atmosphere detection sensing array. Background technique [0002] Domestic and foreign drug detection technologies mainly include: 1) Electrochemical detection method: For example, in 2012, Aso Navaee1 used graphene nanosheets to modify glassy carbon electrodes to simultaneously detect morphine, narcotin, and heroin. This method was first reported based on their In 2013, Zhengzhou University Baoxian Ye et al. manufactured a new morphine electrochemical sensor based on composite graphene and perfluorosulfonic acid membrane modified glassy carbon electrode, which significantly improved its Sensitivity; Toshiyasu et al. used chemically modified chiral capillary electrophoresis / dual mass spectrometry to detect amphetamines. 2) Chromatography: For example, Feng Lu of the Second Military Medical University combined thin-layer c...
