Abstract
The invention provides a drug detection device and method based on microfluidics, and relates to the technical field of micro-fluidic chip, the device comprises a current measuring unit and a micro-fluidic chip arranged on a glass slide, one end of the interior of the micro-fluidic chip is provided with a first liquid storage tank and a second liquid storage tank, a third liquid storage tank and a fourth liquid storage tank are arranged at the other end of the interior of the micro-fluidic chip, the first micro-channel and the second micro-channel are connected through a molecular imprinting channel, two interfaces are arranged at the output end of the current measuring unit, the interfaces are connected with two electrodes through wires respectively, and the electrodes are arranged in the first liquid storage tank and the third liquid storage tank respectively. According to the drug detection method, the response speed is high, the transmission time of ions in the channel is short, and a voltage-current curve can be measured within a few minutes, so that drug molecules in a sample can be detected, the concentration of the corresponding drug molecules is further obtained, and the detection time is greatly shortened.
Description
technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a drug detection device and method based on microfluidics. Background technique [0002] As people's life and work pressure continue to increase, more and more people begin to seek spiritual needs. Under the temptation of the external adverse environment, they gradually become addicted to drugs, which eventually leads to the fragmentation of their families. Therefore, in order to severely crack down on drug crimes, it is necessary to have more accurate and rapid detection methods that can carry out quantitative and qualitative analysis of drugs, so as to quickly determine the types of drugs and provide the most favorable clues for cracking down on drug criminals. At this stage, with the continuous development of science and technology, drug detection methods are emerging in an endless stream. Good detection methods can more accurately identify the ingredients and types...
