Abstract

The invention discloses a multi-object disc type lateral flow test paper chip, a laser cutting preparation method, a use method, an application and a detection device thereof. Multiple hydrophilic channels connected with a probe storage pad are arranged on a disc hydrophobic base plate, so that the purpose of simultaneously detecting multiple objects can be achieved and integration and optimization of experimental result can be conveniently performed; quantity of channels, length of channels, detection type and the like can be designed according to different detection requirements, so that thedeveloping performance is strong; the capillary action is utilized to guide liquid flow, no additional liquid driving device is required, the biological compatibility is high and the post-processingis simple; size and shape of each zone of the test paper chip are designed according to the test requirements of to-be-detected objects; a laser cutting technology adopted for preparing the test paperchip has the characteristics of simple and convenient operation, short preparation period, low energy consumption, high precision and high repeatability; the multi-object disc type lateral flow testpaper chip can be used as a miniature and quick onsite fast detection instrument and especially has an excellent application prospect in the fields of clinical diagnosis, food hygiene, environment monitoring, biological chemistry and the like.

Description

Technical field [0001] The invention belongs to the technical field of environment, food safety and biomedical related detection, and specifically relates to a multi-target dish-type lateral flow test paper chip and its laser cutting preparation method, use method, application and detection device. Background technique [0002] Fast, sensitive, and portable multi-target detection methods have received more and more attention in the fields of environmental monitoring, food safety and biomedical detection. For example, pathogens, heavy metal ions, bacteria and other toxic substances are important indicators of water quality evaluation; in addition, as one of the most concerned issues of global public health, food-borne diseases are often caused by different types of pollutants (such as bacteria, antibiotics, illegal Additives and pesticide residues) contaminated food, which causes one-tenth of the population to get sick every year; in addition, in disease detection, doctors usually...
