“…Zhang et al established an upconversion nanosensor based on magnetic separation and electrostatic adsorption, and was successfully applied for TC detection in food samples. 36 The linear detection range of TC was 0.5–10 3 ng mL −1 , and the LOD was 0.17 ng mL −1 . Electrochemical biosensors have simple operation, high sensitivity, and good selectivity.…”

“…Tetracycline is a broad‐spectrum antibiotic to inhibit bacterial protein synthesis and is effective against both gram‐positive and gram‐negative bacteria (Y. Zhang et al., 2022). Moreover, tetracycline can also promote animal growth and is widely used in animal husbandry and aquaculture as a feed additive (Guo & Cai, 2020).…”

Food safety has always been a hot issue of social concern, and biosensing has been widely used in the field of food safety detection. Compared with traditional aptamer-based biosensors, aptamer-based riboswitch biosensing represents higher precision and programmability. A riboswitch is an elegant example of controlling gene expression, where the target is coupled to the aptamer domain, resulting in a conformational change in the downstream expression domain and determining the signal output. Riboswitch-based biosensing can be extensively applied to the portable real-time detection of food samples. The numerous key features of riboswitch-based biosensing emphasize their sustainability, renewable, and testing, which promises to transform engineering applications in the field of food safety. This review covers recent developments in riboswitch-based biosensors. The brief history, definition, and modular design (regulatory mode, reporter, and expression platform) of riboswitch-based biosensors are explained for better insight into the design and construction. We summarize recent advances in various riboswitch-based biosensors involving theophylline, malachite green, tetracycline, neomycin, fluoride, thrombin, naringenin, ciprofloxacin, and paromomycin, aiming to provide general guidance for the design of riboswitch-based biosensors. Finally, the challenges and prospects are also summarized as a way forward stratagem and signs of progress.

“…In the aptamer‐based detection methods, the unlabeled aptamers are more convenient than the labeled aptamers because no dye molecules are used in aptamer, thereby reducing the possible errors in the entire experiment process (Xia et al., 2018). Unlabeled aptamers can be used for the enrichment and purification of targets, and specific detection can also be performed according to the signal changes after the capture of target (Jia et al., 2022; Y. L. Zhang et al., 2022).…”

Chemical contaminants in food generally include natural toxins (mycotoxins, animal toxins, and phytotoxins), pesticides, veterinary drugs, environmental pollutants, heavy metals, and illegal additives. Developing a low-cost, simple, and rapid detection technology for harmful substances in food is urgently needed. Analytical methods based on different advanced materials have been developed into rapid detection methods for food samples. In particular, photonic crystal (PC) materials have a unique surface periodic structure, structural color, a large surface area, easy integration with photoelectronic and magnetic devices which have great advantages in the development of rapid, low-cost, and highly sensitive analytical methods. This review focuses on the PC materials in the view of their fabrication processes, functionalized recognition components for the specific recognition of hazardous substances, and applications in the separation, enrichment, and detection of chemical hazards in real samples. Suspension array based on three-dimensional PC microspheres by droplet-based microfluidic assembly is a great promising and powerful platform for food safety detection fields. For the PCs selective analysis, biological antibodies, aptamers, and molecularly imprinted polymers (MIPs) could be modified for specific recognition of target substances, particularly MIPs because of their low-cost and easy mass production. Based on these functional PCs, various toxic and hazardous substances can be selectively enriched or recognized in real samples and further quantified in combination of liquid chromatography method or optical detection methods including fluorescence, chemiluminescence, and Raman spectroscopy.
