“…H5N1, Avian influenza virus, is determined by different methods such as the immunochromatography, the reversetranscription PCR (RT-PCR), ELISA, serological methods [9], quartz crystal microbalance, surface plasmon resonance, and fluorescence. However, the electrochemical detection method received high attention because of providing low cost, small sample volume without amplification step, and user-friendly interface and portability [118].…”

“…There are various immobilization techniques of antibodies, such as straight adsorption on the electrode surface, magnetic beads (MBs) or polymer matrices, SAMs, etc., that can be used. Among these techniques, SAMs of alkanethiols are widely applied techniques because this technique provides an easy way to produce strong covalent bonds, controlled arrangement, ultrathin, oriented and ordered monolayer on the surface of the electrode ( Haji-Hashemi et al, 2017 ). Monolayers of metals like gold, silver with the sulfur compound are able to give a proper immobilization of biomolecule.…”

Last few decades, viruses are a real menace to human safety. Therefore, the rapid identification of viruses should be one of the best ways to prevent an outbreak and important implications for medical healthcare. The recent outbreak of coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus which belongs to the single-stranded, positive-strand RNA viruses. The pandemic dimension spread of COVID-19 poses a severe threat to the health and lives of seven billion people worldwide. There is a growing urgency worldwide to establish a point-of-care device for the rapid detection of COVID-19 to prevent subsequent secondary spread. Therefore, the need for sensitive, selective, and rapid diagnostic devices plays a vital role in selecting appropriate treatments and to prevent the epidemics. During the last decade, electrochemical biosensors have emerged as reliable analytical devices and represent a new promising tool for the detection of different pathogenic viruses. This review summarizes the state of the art of different virus detection with currently available electrochemical detection methods. Moreover, this review discusses different fabrication techniques, detection principles, and applications of various virus biosensors. Future research also looks at the use of electrochemical biosensors regarding a potential detection kit for the rapid identification of the COVID-19.

“…[78][79][80][81][82] Assays targeting viral antigens.-Haji-Hashemi et al presented the first label-free electrochemical immunosensor to detect CTV antigens. 83 First, a gold electrode was modified using 11-mercaptoundecanoic acid (MUA) and 3-mercaptopropionic acid (MPA). Then, the terminal carboxylic groups on surface of the modified electrode were activated using N-(3-dimethylaminopropyl)-Nethyl carbodiimide hydrochloride (EDC) and N-hydroxysuccinamide (NHS).…”

Infectious diseases commonly occur in contaminated water, food, and bodily fluids and spread rapidly, resulting in death of humans and animals worldwide. Among infectious agents, viruses pose a serious threat to public health and global economy because they are often difficult to detect and their infections are hard to treat. Since it is crucial to develop rapid, accurate, cost-effective, and in-situ methods for early detection viruses, a variety of sensors have been reported so far. This review provides an overview of the recent developments in electrochemical sensors and biosensors for detecting viruses and use of these sensors on environmental, clinical and food monitoring. Electrochemical biosensors for determining viruses are divided into four main groups including nucleic acid-based, antibody-based, aptamer-based and antigen-based electrochemical biosensors. Finally, the drawbacks and advantages of each type of sensors are identified and discussed.
