Intelligent biosensing strategies for rapid detection in food safety: A review

Luminescent Guests Encapsulated in Metal–Organic Frameworks for Portable Fluorescence Sensor and Visual Detection Applications: A Review

“…Smartphones can more accurately detect the color difference on each pixel, by calculating RGB (red, green, and blue) values. Compared with traditional methods, the portable sensing platform based on smartphones has obvious advantages such as low cost, real-time response, easy operation, accurate measurement, and portability, and has been widely used in clinical diagnosis [ 103 , 104 , 105 , 106 ], environmental monitoring [ 107 , 108 , 109 , 110 ] and food analysis [ 111 , 112 , 113 ]. Researchers have been actively engaged in fluorescence measurements compatible with smartphones, to develop on-site sensing platforms for quantitative detection.…”

Stimulus-Responsive DNA Hydrogel Biosensors for Food Safety Detection

“…Many attempts have been made, but the existing methods still have certain shortcomings. Traditional methods such as culture and colony counting are less efficient and sensitive [ 29 ]. Other methods such as enzyme-linked immunoassay (ELISA), polymerase chain reaction (PCR) and high-performance liquid chromatography (HPLC), despite having improved sensitivity, are still not suitable for on-site detection or field use due to the complexity and poor portability of the instruments [ 30 , 31 ].…”

Oxidation activity modulation of a single atom Ce-N-C nanozyme enabling a time-resolved sensor to detect Fe3+ and Cr6+

“…6,7 Hence, the future of food safety depends on the development of tools for rapid real-time and portable detection. [8][9][10][11][12] The rapid detection of heavy metal ions based on enzyme mimics has recently attracted much interest. 13,14 In order to overcome the problem of low activity of the widely used nanozymes which is caused by the diversity of structures and unevenly distributed elements of nanozymes, [15][16][17] novel single atom nanozymes (SAzymes) have been constantly developed.…”
