“…The early detection of viruses is essential for the prevention and treatment of the associated diseases ( Ambinder et al, 2010 ). Many diagnostic techniques have been developed for virus detection involving quantitative PCR (qPCR) ( Pansri et al, 2020 ), real-time RCR (rtPCR) ( Corman et al, 2020 ), nucleic acid amplification tests ( Xie et al, 2020 ), high-throughput sequencing ( Massart et al, 2018 ), IgM-IgG combined antibody testing ( Li et al, 2020c ), IgA antibody ( Lu et al, 2020 ) and antigen testing ( Yang et al, 2020 ), electrochemical sensors ( Bukkitgar and Shetti 2016a , 2016b ; Bukkitgar et al, 2020 ; Kumar et al, 2019 ; Shetti et al 2019b , 2019d ), etc. However, most of the assays are high cost and need tedious sample processes.…”

Virus severely endangers human life and health, and the detection of viruses is essential for the prevention and treatment of associated diseases. Metal-organic framework (MOF), a novel hybrid porous material which is bridged by the metal clusters and organic linkers, has become a promising biosensor platform for virus detection due to its outstanding properties including high surface area, adjustable pore size, easy modification, etc. However, the MOF-based sensing platforms for virus detection are rarely summarized. This review systematically divided the detection platforms into nucleic acid and immunological (antigen and antibody) detection, and the underlying sensing mechanisms were interpreted. The nucleic acid sensing was discussed based on the properties of MOF (such as metal ion, functional group, geometry structure, size, porosity, stability, etc.), revealing the relationship between the sensing performance and properties of MOF. Moreover, antibodies sensing based on the fluorescence detection and antigens sensing based on molecular imprinting or electrochemical immunoassay were highlighted. Furthermore, the remaining challenges and future development of MOF for virus detection were further discussed and proposed. This review will provide valuable references for the construction of sophisticated sensing platform for the detection of viruses, especially the 2019 coronavirus.

Lab-on-a-chip sensing technologies have changed how cell biology research is conducted. This review summarises the progress in the lab-on-a-chip devices implemented for the detection of cellular metabolites. The review is divided into two subsections according to the methods used for the metabolite detection. Each section includes a table which summarises the relevant literature and also elaborates the advantages of, and the challenges faced with that particular method. The review continues with a section discussing the achievements attained due to using lab-on-a-chip devices within the specific context. Finally, a concluding section summarises what is to be resolved and discusses the future perspectives.

“…The acoustic (piezoelectric) impulse response parameters (dominant frequency, firmness index, and elasticity coefficient) yielded a good to strong correlation with firmness parameters (compression force and puncture force) of tomatoes during storage time [ 131 ]. Electrochemical sensors are devices that convert electrochemical reactions between an electrode and analyte into an output signal specifically related to the concentration or partial pressure of the gaseous species [ 132 ]. The types of electrochemical sensors include potentiometric, conductometric, amperometric, and voltametric but they have limited detection limits [ 130 , 132 – 134 ].…”

The environment and food safety are major areas of concern influencing the development of biodegradable packaging for partial replacement of petrochemical-based polymers. This review is aimed at updating the recent advances in biodegradable packaging material and the role of virtual technology and nanotechnology in the tomato supply chain. Some of the common biodegradable materials are gelatin, starch, chitosan, cellulose, and polylactic acid. The tensile strength, tear resistance, permeability, degradability, and solubility are some of the properties defining the selection and utilization of food packaging materials. Biodegradable films can be degraded in soil by microbial enzymatic actions and bioassimilation. Nanoparticles are incorporated into blended films to improve the performance of packaging materials. The prospects of the fourth industrial revolution can be realized with the use of virtual platforms such as sensor systems in authentification and traceability of food and packaging products. There is a research gap on the development of a hybrid sensor system unit that can integrate sampling headspace (SHS), detection unit, and data processing of big data for heterogeneous tomato-derived volatiles. Principal component analysis (PCA), linear discriminant analysis (LDA), and artificial neutral network (ANN) are some of the common mathematical models for data interpretation of sensor systems.
