Abstract

The invention discloses preparation and application of a simple high-throughput microfluidic chemiluminescence paper chip. A plurality of microfluidic chemiluminescence paper chips are printed in batches on B5 plain filter paper by using a full print mode. The printing process comprises batch printing of hydrophobic wax patterns, melted wax molding, bath printing of chemiluminescence reagent ink patterns, batch printing of oxidase ink patterns, bath printing of flow rate adjusting hydrophobic wax patterns, laser cutting of microfluidic chemiluminescence paper chips, and plastic sealing treatment of the prepared microfluidic chemiluminescence paper chips. A field test method of the microfluidic chemiluminescence paper chip comprises the following steps: placing the plastic-sealed microfluidic chemiluminescence paper chips in a cassette of a palm light emitting testing instrument; dropwisely adding a sample solution to a sampling area; closing a cassette cover, and starting testing. The existence and contents of 32 kinds of tested components are determined by the sizes of 32 successively appearing chemiluminescence peak values.

Description

technical field [0001] The invention relates to the technical field of simple, cheap and high-throughput on-site analysis and detection, and more specifically relates to the construction of a microfluidic paper-on-a-chip laboratory technology platform based on a chemiluminescence analysis method. Background technique [0002] Food safety, major human diseases, major livestock and poultry diseases in the aquaculture industry, environmental persistent pollutants, and environmental hormones directly affect people's health and life safety. Therefore, it is necessary to strengthen food quality and safety control, establish an analysis platform for harmful substances such as pesticide residues in food, carry out early diagnosis and prevention of major diseases such as malignant tumors, strengthen research on efficient prevention and control technologies for livestock and poultry diseases, and develop simple, sensitive and specific diagnostic technologies It is a problem that needs...
