“…However, the ability of electrochemical sensors to detect inappropriate levels is still limited due to the weak signal of pharmaceutical and biological compounds on the surface of unmodified sensors (Karimi-Maleh et al, 2017, 2020aGhanei-Motlagh and Baghayeri, 2020;Nodehi et al, 2020). With the replacement of simple sensors with electrochemical modified sensors in recent years, it has been possible to sensitively and selectively measure important drug compounds, especially anticancer drugs (Karimi-Maleh et al, 2019a;Khodadadi et al, 2019;Baghayeri et al, 2020;Karimi-Maleh and Arotiba, 2020;Mohanraj et al, 2020). Nanomaterials with new and wonderful features are important options in various fields in recent years (Rayati and Malekmohammadi, 2016;Asl, 2017;Malekmohammadi et al, 2018a,b;Orooji et al, 2019a,b,c;Karimi-Maleh et al, 2020c;Nguyen et al, 2020).…”

Measuring the concentration of anticancer drugs in pharmacological and biological samples is a very useful solution to investigate the effectiveness of these drugs in the chemotherapy process. A Pt,Pd-doped, NiO-decorated SWCNTs (Pt,Pd-NiO/SWCNTs) nanocomposite was synthesized using a one-pot procedure and combining chemical precipitation and ultrasonic sonochemical methods and subsequently characterized by TEM and EDS analysis methods. The analyses results showed the high purity and good distribution of elements and the ~10-nm diameter of the Pt,Pd-NiO nanoparticle decorated on the surface of the SWCNTs with a diameter of about 20–30 nm. Using a combination of Pt,Pd-NiO/SWCNTs and 1-butyl-2,3-dimethylimidazolium tetrafluoroborate (1B23DTFB) in a carbon paste (CP) matrix, Pt,Pd-NiO/SWCNTs/1B23DTFB/CP was fabricated as a highly sensitive analytical tool for the electrochemical determination of daunorubicin in the concentration range of 0.008–350 μM with a detection limit of 3.0 nM. Compared to unmodified CP electrodes, the electro-oxidation process of daunorubicin has undergone significant improvements in current (about 9.8 times increasing in current) and potential (about 110 mV) decreasing in potential). It is noteworthy that the designed sensor can well measure daunorubicin in the presence of tamoxifen (two breast anticancer drugs with a ΔE = 315 mV. According to the real sample analysis data, the Pt,Pd-NiO/SWCNTs/1B23DTFB/CP has proved to be a promising methodology for the analysis and measuring of daunorubicin and tamoxifen in real (e.g., pharmaceutical) samples.

“…Sensing and biosensing platforms for detecting viruses [ 32 – 36 ] are considered as ideal and outstanding approaches for providing reliable and alternative solutions for real-time diagnostic and continuous monitoring purposes. In recent years, sensing and biosensing assays have attracted great attention as useful and appropriate tools for point-of-care applications because of their rapid response, high sensitivity, low detection limits, portability, and easy fabrication process [ 37 , 38 ]. Various sensing and biosensing platforms for virus detection have recently been developed.…”

A novel coronavirus of zoonotic origin (SARS-CoV-2) has recently been recognized in patients with acute respiratory disease. COVID-19 causative agent is structurally and genetically similar to SARS and bat SARS-like coronaviruses. The drastic increase in the number of coronavirus and its genome sequence have given us an unprecedented opportunity to perform bioinformatics and genomics analysis on this class of viruses. Clinical tests like PCR and ELISA for rapid detection of this virus are urgently needed for early identification of infected patients. However, these techniques are expensive and not readily available for point-of-care (POC) applications. Currently, lack of any rapid, available, and reliable POC detection method gives rise to the progression of COVID-19 as a horrible global problem. To solve the negative features of clinical investigation, we provide a brief introduction of the general features of coronaviruses and describe various amplification assays, sensing, biosensing, immunosensing, and aptasensing for the determination of various groups of coronaviruses applied as a template for the detection of SARS-CoV-2. All sensing and biosensing techniques developed for the determination of various classes of coronaviruses are useful to recognize the newly immerged coronavirus, i.e., SARS-CoV-2. Also, the introduction of sensing and biosensing methods sheds light on the way of designing a proper screening system to detect the virus at the early stage of infection to tranquilize the speed and vastity of spreading. Among other approaches investigated among molecular approaches and PCR or recognition of viral diseases, LAMP-based methods and LFAs are of great importance for their numerous benefits, which can be helpful to design a universal platform for detection of future emerging pathogenic viruses.

“…Besides the cost of the electrodes, the key technical factors that determine the applicability of ECBs in clinical purposes are: ease of preparation, sensitivity, accuracy, ECBs can be manufactured in miniaturized size that can be used as POCT devices for clinical purposes [45,46]. These POCT devices are often fabricated on paper strips or carbon paste electrodes based on lab-on-chip principles and can be used with a portable electroanalytical device [46,47]. Electrochemical glucose biosensors are one of the most successful and promising examples of this technology [48].…”

With the rise in public health awareness, research on point-of-care testing (POCT) has significantly advanced. Electrochemical biosensors (ECBs) are one of the most promising candidates for the future of POCT due to their quick and accurate response, ease of operation, and cost effectiveness. This review focuses on the use of metal nanoparticles (MNPs) for fabricating ECBs that has a potential to be used for POCT. The field has expanded remarkably from its initial enzymatic and immunosensor-based setups. This review provides a concise categorization of the ECBs to allow for a better understanding of the development process. The influence of structural aspects of MNPs in biocompatibility and effective sensor design has been explored. The advances in MNP-based ECBs for the detection of some of the most prominent cancer biomarkers (carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), Herceptin-2 (HER2), etc.) and small biomolecules (glucose, dopamine, hydrogen peroxide, etc.) have been discussed in detail. Additionally, the novel coronavirus (2019-nCoV) ECBs have been briefly discussed. Beyond that, the limitations and challenges that ECBs face in clinical applications are examined and possible pathways for overcoming these limitations are discussed.
