“…These viruses spread through birds and mammals by means of fomites or through aerogenic as well as fecal-oral courses [7]. However, recent whole genome sequence reports suggested that the virus present in bats were found to be 79.5% similar with SARS-CoV thus indicating that viruses could have been transmitted from the bats through an intermediate host which emphasize the fact that bats as the most probable host of SARS-CoV2 in transmission of the disease to humans [16]. The virus is usually transmitted at a much faster rate via air-droplets that occur due to coughing or sneezing of an infected individual.…”

The severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), is spreading worldwide rapidly from its original city of China. Corona virus has the presence of positive sense Ribonucleic acid (RNA) genetic material. The infection causes mild respiratory disease especially in humans across all age groups. The widespread distribution of corona virus in other organisms such as birds, livestock and mammals such as bats, pangolins etc. makes it an important pathogen of concern. It has also been reported the number of people that act as healthy carriers of the virus are approximately 2%, where they do not show any symptoms of the infection but act as a prime source of transmission. Transmission of the virus is usually through large droplets generated during sneezing and coughing and thus can remain viable for several days in favorable atmospheric conditions but can be controlled by the usage of disinfectants. World Health Organization recommends isolation as most efficacious method for the containment of patients that are affected by this virus. At present, there are no particular anti-viral medications or vaccines are correctly present to suppress this infection from spreading. However, Polymerase chain reaction (PCR) methods have proved to be effective for assessing viral RNA but may prove to be very time-consuming assay. Thus, as per the present scenario, more research should be carried out to develop a rapid, user-friendly, diagnostic assay which has high specificity and sensitivity at mass level screening thus enabling the further process of drug designing.

“…13,14 However, in order to enhance the signal, a variety of redox mediators and enzymes as well as aptamers are used to modify the electrode, which potentially increase the complexity and cost of the methods. 15,16 In addition, biological enzymes usually have poor stability and cannot work in harsh environments. For this reason, there is an urgent need to nd a novel nanozyme-based multifunctional probe with intrinsic redox activity, good biocompatibility and catalytic properties to overcome the limitations associated with current electrochemical devices.…”

“…Other than metal nanoparticles, carbon-based materials have also become highly attractive in the development of an electrochemical sensing platform (e.g., graphene and its derivatives and carbon nanotubes), mostly due to their favorable characteristics such as excellent performance, high mechanical strength, and thermal stability [32][33][34]. Moreover, peptide molecules and oligonucleotides-called aptamers-have been developed, which have received significant attention in biosensor modification strategies because they enable high-affinity binding to a specific target molecule and can convert biorecognition cues into electrochemical signals [35].…”

Electrochemical sensors are considered an auspicious tool to detect biomolecules (e.g., DNA, proteins, and lipids), which are valuable sources for the early diagnosis of diseases and disorders. Advances in electrochemical sensing platforms have enabled the development of a new type of biosensor, enabling label-free, non-destructive detection of viability, function, and the genetic signature of whole cells. Numerous studies have attempted to enhance both the sensitivity and selectivity of electrochemical sensors, which are the most critical parameters for assessing sensor performance. Various nanomaterials, including metal nanoparticles, carbon nanotubes, graphene and its derivatives, and metal oxide nanoparticles, have been used to improve the electrical conductivity and electrocatalytic properties of working electrodes, increasing sensor sensitivity. Further modifications have been implemented to advance sensor platform selectivity and biocompatibility using biomaterials such as antibodies, aptamers, extracellular matrix (ECM) proteins, and peptide composites. This paper summarizes recent electrochemical sensors designed to detect target biomolecules and animal cells (cancer cells and stem cells). We hope that this review will inspire researchers to increase their efforts to accelerate biosensor progress—enabling a prosperous future in regenerative medicine and the biomedical industry.
