“…In particular, the importance of developing and researching biosensors that do not give false-negative results for viruses that are at risk of rapid transmission and have lethal effects, which is another problem for humanity, has been understood. Dai et al reported the development of a novel COVID-19 biosensor highly-sensitive and rapid enzymatic detection of the COVID-19 spike antigen without sample labeling for the accurate and rapid diagnosis of SARS-CoV-2 infection [11]. In this study, the anti-SARS-CoV-2 spike monoclonal antibodies were immobilized onto the surface of biosensor for the specific recognition of the SARS-CoV-2 spike antigen.…”

In recent years, there has been significant interest in advanced nanobiosensor technologies with their exceptional properties for real-time monitoring, ultra-sensing, and rapid detection. With relevant experimental data, highly selective and hypersensitive detection of various analytes is possible using biosensors based on nanostructures. In particular, biosensors focus on vital issues such as disease early diagnosis and treatment, risk assessment of quality biomarkers, food-water quality control, and food safety. In the literature, there has been great attention to the preparation and sensing behavior of several nanomaterials-based sensors, such as polymer frameworks, metal-organic frameworks, one-dimensional (1D) nanomaterials, two-dimensional (2D) nanomaterials, and MXenes-based sensors. This chapter gives points to all aspects of fabrication, characterization, mechanisms, and applications of nanostructures-based biosensors. Finally, some smart advanced sensing systems for ultra-sensing nanoplatforms, as well as a comprehensive understanding of the sensor performances, current limitations, and future outlook of next-generation sensing materials, are highlighted.

The pandemic caused by SARS-CoV-2 has a huge impact on the global economy. SARS-CoV-2 could possibly and potentially be transmitted to humans through cold-chain foods and packaging (namely good-to-human), although it mainly depends on a human-to-human route. It is imperative to develop countermeasures to cope with the spread of viruses and fulfil effective surveillance of cold-chain foods and packaging. This review outlined SARS-CoV-2-related cold-chain food incidents and current methods for detecting SARS-CoV-2. Then the needs, challenges and practicable countermeasures for SARS-CoV-2 detection, specifically for cold-chain foods and packaging, were underlined. In fact, currently established detection methods for SARS-CoV-2 are mostly used for humans; thus, these may not be ideally applied to cold-chain foods directly. Therefore, it creates a need to develop novel methods and low-cost, automatic, mini-sized devices specifically for cold-chain foods and packaging. The review intended to draw people’s attention to the possible spread of SARS-CoV-2 with cold-chain foods and proposed perspectives for futuristic cold-chain foods monitoring during the pandemic.

“…Dai et al developed a label-free surface plasmon resonance based on laser heterodyne feedback interferometry that detects SARS-CoV-2 S protein from patients’ samples. This sensor measures the change in the refractive index in response to antigen-antibody interactions in real-time, with a detection limit of as little as 0.08 pg/mL ( Dai et al, 2022 ). Another optical biosensor detects IgG levels in patients’ serum samples using the photoluminescence spectroscopy principle.…”
