Special Issue Information

Dear Colleagues,

Agri-food is essential to sustain life. The worldwide agri-food market has grown rapidly recently due to tremendous biological, chemical, and physical threats to food products. There are large amounts of consumers demanding processing monitoring and quality and safety control of these products. Consequently, farmers and industries are adopting various technological methodologies for the facile, effective, and efficient analysis of hazardous chemical compounds or bio-entities in food products.

The recent advances in biodevice engineering and developments of biosensing methodologies promote biosensors as an emerging tool in the food quality and safety monitoring field. The advantages of biosensors over traditional methods include their sensitivity, selectivity, durability, simplicity of operation, portability, and time and economic efficiency.

Both review and original research papers are encouraged, and potential topics include, but are not limited to, the following:

  • Immunosensor applications in biohazard monitoring;
  • Development of oligonucleotide sensors in food safety;
  • Affinity-based biosensor applications as food quality indicators;
  • State of the art and new challenges in SELEX for aptasensing applications;
  • New trends in nanomaterial fabrication for biosensing applications;
  • Microfluidic and microarray in manufacturing of biosensing devices;
  • The synthesis of other materials (polymer, MOF, COF, HOF, etc.) in environmental and food safety.

Ofloxacin (OFL) is widely used in animal husbandry and aquaculture due to its low price and broad spectrum of bacterial inhibition, etc. However, it is difficult to degrade and is retained in animal-derived food products, which are hazardous to human health. In this study, a simple and efficient method was developed for the detection of OFL residues in meat products. OFL coupled with amino magnetic beads by an amination reaction was used as a stationary phase. Aptamer AWO-06, which showed high affinity and specificity for OFL, was screened using the exponential enrichment (SELEX) technique. A fluorescent biosensor was developed by using AWO-06 as a probe and graphene oxide (GO) as a quencher. The OFL detection results could be obtained within 6 min. The linear range was observed in the range of 10–300 nM of the OFL concentration, and the limit of the detection of the sensor was 0.61 nM. Furthermore, the biosensor was stored at room temperature for more than 2 months, and its performance did not change. The developed biosensor in this study is easy to operate and rapid in response, and it is suitable for on-site detection. This study provided a novel method for the detection of OFL residues in meat products. Full article
