Applications of Microfluidic Technology in Marine Analysis and Monitoring

In the process of cognizing the laws of the ocean, developing marine economy, protecting and restoring the marine ecological environment, marine analysis and monitoring are essential technology. Modern ocean monitoring presents the characteristics of in-situ, on-site, and comprehensive. Small, sensitive, rapid, and automated analysis and monitoring equipment is urgently required. Microfluidic chip technology, with its outstanding characteristics of micro channel control, low-cost, and high throughput, combined with advanced chemical analysis methods, has shown excellent prospects in the construction of core sensing components of marine analysis and monitoring equipment. This review described the materials and preparation of microfluidic chips and the construction of analytical methods, focusing on two types of applications, marine environmental analysis and marine in-situ online monitoring, involving pH, dissolved gases, nutrients, heavy metals, organic pollutants and marine microorganisms. This review summarized the application progress of microfluidic technology in marine analysis and monitoring, and provided an outlook on future development.
