Application of colorimetric paper-based microfluidic chip in rapid food safety detection

Paper-based microfluidic chip (P-chip) is a new kind of integrated, portable and inexpensive detection technology. In the design process, it can be combined with traditional detection methods to realize more detection in applied scenes. Combined with colorimetric assay, the P-chip obtains many advantages, such as low manufacturing cost, short detection time, convenient for carrying and easy to observe results, which can meet the requirements of large quantities and short time detection. The P-chip has been widely used in environmental detection, food safety and quality control, clinical diagnosis, etc. This paper mainly introduced the manufacturing technology, detection method and application in food detection field of colorimetric microfluidic paper chip, including analysis of food components, detection of pesticide residues, pathogenic bacteria, heavy metals and food additives, etc. At the same time, the processing technology and application prospect of colorimetric microfluidic paper chip were prospected.
