Abstract
Electrically addressable covalent immobilization of probes on a multiplexed electrode for the simultaneous detection of multiple targets within the same sample is often regarded as a difficult milestone to be achieved. Herein, we demonstrated a reagentless disposable multiplexed electrochemical DNA and aptamer-based sensing platform for the simultaneous determination of various targets. The electrochemically triggered "click" chemistry was developed, and three biomarkers, including p53, thrombin, and VEGF165 were used as model analytes. The proposed sensor consisted of three independent screen-printed carbon electrodes (SPCE), with an alkyne-azide cycloaddition reaction that was activated selectively by means of electrical triggering, so that different DNA probes can be modified on the desired electrode units in sequence. In terms of simultaneous detection, the sensor was able to quantify the DNA target of p53 with a detection limit of 0.35 nM, whereas the limits of detection for protein quantification of thrombin and VEGF165 were 0.22 nM and 0.014 nM, respectively. The proposed sensor not only showed encouraging reproducibility and stability, but also performed well even in 50% serum samples. Therefore, the work described here offers a general strategy for developing a multiplexed sensor with promising potential to achieve rapid, simple and cost-effective analysis of biological samples.

Abstract
The pandemic of coronavirus disease 2019 (COVID-19) highlights the importance of rapid and sensitive diagnostics of viral infection that enables the efficient tracing of cases and the implementation of public health measures for disease containment. The immediate actions from both academia and industry have led to the development of many COVID-19 diagnostic systems that have secured fast-track regulatory approvals and have been serving our healthcare frontlines since the early stage of the pandemic. On diagnostic technologies, many of these clinically validated systems have significantly benefited from the recent advances in micro- and nanotechnologies in terms of platform design, analytical method, and system integration and miniaturization. The continued development of new diagnostic platforms integrating micro- and nanocomponents will address some of the shortcomings we have witnessed in the existing COVID-19 diagnostic systems. This Perspective reviews the previous and ongoing research efforts on developing integrated micro- and nanosystems for nucleic acid-based virus detection, and highlights promising technologies that could provide better solutions for the diagnosis of COVID-19 and other viral infectious diseases. With the summary and outlook of this rapidly evolving research field, we hope to inspire more research and development activities to better prepare our society for future public health crises.

Abstract
In this study, an automatic glycated hemoglobin (HbA1c) impedance measurement system (AHMS) is developed for the detection of HbA1c. The proposed device removes some of the drawbacks of common instruments for HbA1c detection (i.e., large, expensive, difficult to operate) by detecting the ratio of HbA1c to Hb. The method is label-free and requires only a small sample volume; no additional reagents are required. The manpower consumption and bulk of the instrument are also reduced. The method provides a simple way to analyze impedance deviation and effectively reduces the effort required by the operator. The ratios of HbA1c to Hb (4%-7%) are well distinguished, and the experiment is used to build a database for AHMS. To check the reliability of the proposed system, a sample test using three different ratios of HbA1c is applied in this study. The sample test uses HbA1c to Hb ratios of 4.7%, 5.6%, and 6.8%, and the determined experimental values are 4.93%, 5.8%, and 6.83%, respectively. The sample test has an accuracy of approximately 96.99%. Based on these results, the proposed system for detecting HbA1c through protein coverage is both effective and feasible.

Abstract
The detection of mismatched base pairs in DNA plays a crucial role in the diagnosis of genetic-related diseases and conditions, especially for early stage treatment. Among the various biosensors that have been used for DNA detection, EC sensors show great promise because they are capable of precise DNA recognition and efficient signal transduction. Advancements in micro- and nanotechnologies, specifically fabrication techniques and new nanomaterials, have enabled for the development of highly sensitive, highly specific sensors making them attractive for the detection of small sequence variations. Furthermore, the integration of sensors with sample preparation and fluidic processes enables for rapid, multiplexed DNA detection essential for POC clinical diagnostics.

Abstract
A rapid, simple and low-cost method for the detection of known mutations in DNA oligonucleotide in a biothreat agent, Bacillus anthracis, has been reported. The technique is based on fluorescence resonance energy transfer (FRET), that utilizes a cationic conjugated polymer and a PNA probe labeled with Fluorescein dye (PNAC*). When the PNA probe is hybridized with a complementary target ssDNA and its mutated sequences separately, the energy transfer from polymer to PNAC*/ssDNA complex decreases with increasing number of mutations. It means that the efficiency of FRET or the degree of hybridization depends on the extent of mutations in the DNA sequence. The method is sensitive enough to detect upto 4 bases mismatch. We have, thus, explored a possible application of fluorescence-based technology for medical diagnostics.

Abstract
A novel method for the future development of label-free DNA sensors is proposed here. The approach is based on the displacement of a labelled suboptimum mutated oligonucleotide hybridised with the immobilised biotin-capture probe. The target fully complementary to the biotin-capture probe can displace the labelled oligonucleotide causing a subsequent decrease of the signal that verifies the presence of the target. The decrease of signal was demonstrated to be proportional to the target concentration. A study of the hybridisation of mutated and complementary labelled oligonucleotides with an immobilised biotin-capture probe was carried out. Different kinetic and thermodynamic behaviour was observed for heterogeneous hybridisation of biotin-capture probe with complementary or suboptimum oligonucleotides. The displacement method evaluated colourimetrically achieved the objective of decreasing the response time from 1 h for direct hybridisation of 19-mer oligonucleotides in the direct enzyme-linked oligonucleotide assay (ELONA) to 5 min in the case of displacement detection in the micromolar concentration range.

Abstract
Clinical diagnosis and disease prevention routinely require the assessment ofspecies determined by chemical analysis. Biosensor technology offers several benefits overconventional diagnostic analysis. They include simplicity of use, specificity for the targetanalyte, speed to arise to a result, capability for continuous monitoring and multiplexing,together with the potentiality of coupling to low-cost, portable instrumentation. This workfocuses on the basic lines of decisions when designing electron-transfer-based biosensorsfor clinical analysis, with emphasis on the strategies currently used to improve the deviceperformance, the present status of amperometric electrodes for biomedicine, and the trendsand challenges envisaged for the near future.

Abstract
The DNA microarray technology is a well-established and widely used technology although it has several drawbacks. The accurate molecular recognition of the canonical nucleobases of probe and target is the basis for reliable results obtained from microarray hybridization experiments. However, the great flexibility of base pairs within the DNA molecule allows the formation of various secondary structures incorporating Watson-Crick base pairs as well as non-canonical base pair motifs, thus becoming a source of inaccuracy and inconsistence. The first part of this report provides an overview of unusual base pair motifs formed during molecular DNA interaction in solution highlighting selected secondary structures employing non-Watson-Crick base pairs. The same mispairing phenomena obtained in solution are expected to occur for immobilized probe molecules as well as for target oligonucleotides employed in microarray hybridization experiments the effect of base pairing and oligonucleotide composition on hybridization is considered. The incorporation of nucleoside derivatives as close shape mimics of the four canonical nucleosides into the probe and target oligonucleotides is discussed as a chemical tool to resolve unwanted mispairing. The second part focuses non-Watson-Crick base pairing during hybridization performed on microarrays. This is exemplified for the unusual stable dG.dA base pair.

Abstract
One of the most time consuming and complex steps in the detection of DNA target with a biosensor is the previous labeling of the target. In this paper, a novel target label-free, reagentless and easy to use DNA biosensor is reported. Electrochemical transduction (cyclic voltammetry, differential pulse voltammetry and impedance spectroscopy) and optical red out by surface plasmon resonance were chosen for the platform optimization. This target label-free DNA detection method is based on displacement of sub-optimum labeled oligonucleotide. This strategy requires the pre-hybridization of the capture probe immobilized on the electrode surface with a sub-optimum mutated oligonucleotide pre-labeled with an electrochemically active ferrocene moiety. Due to the higher affinity of the target that is fully complementary to the capture probe, the sub-optimum ferrocene-labeled sequence is displaced when the fully complementary target is introduced into the system. The decrease of the electrochemical signal from the ferrocene verifies the presence of the target, which is proportional to the target concentration. A variation of this strategy was employed to enhance the ferrocene signal. A diffusional mediator, ferrocyanide, was introduced in the system to help in this purpose. This platform attains a stable, specific and reproducible response (5-15%), with a detection limit in the range of microM. This electrochemical sensor is the first example of this kind of sensor to detect cystic fibrosis, however, this configuration could be generically applied to any application where the detection of a DNA target is involved.

Alkaline phosphatase (AP) is one of the most used enzymatic labels for the development of ELISAs, immunosensors, DNA hybridization assays, etc. This enzyme catalyzes the dephosphorylation of a substrate into a detectable product usually quantified by optical or electrochemical measurements. This work is based on a substrate (3-indoxyl phosphate) that produces a compound able to reduce silver ions in solution into a metallic deposit, which is localized where the enzymatic label AP is attached. The deposited silver is electrochemically stripped into solution and measured by anodic stripping voltammetry. Its application to an enzymatic genosensor on streptavidin-modified screen-printed carbon electrodes for the detection of virulence nucleic acid determinants of autolysin gene, exclusively present on the genome of the human pathogen Streptococcus pneumoniae, is described. Compared with the direct voltammetric detection of indigo carmine, the anodic stripping voltammetry of silver ions is 14-fold more sensitive.

Abstract
The use of thick- and thin film electrodes as supports for genosensor devices offers enormous opportunities for their application in molecular diagnosis. The technologies used in the fabrication of both thick- and thin-film electrodes allow the mass production of reproducible, inexpensive and mechanically robust strip solid electrodes. Other important advantages of these electrodes are the possibility of miniaturization as well as their ease of manipulation in a disposable manner and therefore the use of small volumes. To detect transcriptional profiling and single nucleotide polymorphism thin-film arrays of 14, 20, 25, 48, and 64 electrodes have been fabricated, using lithographic techniques. Readout systems for these arrays based on electrical detection have also been developed. Moreover, a thick-film sensor array suitable for automation combined to readout based on intermittent pulse amperometry (IPA) has been commercialized. These genosensors and the readout instruments provide a simple, accurate and inexpensive platform for patient diagnosis. It is more than probable that arrays for 50–100 DNA sequences will be needed for some clinical applications. Although it is not difficult to design electrode pads with reproducible dimensions of a micron or less, the electrochemical readout requires mechanical connections to each individual electrode.

Abstract
Ferrocenylnaphthalene diimide (FND)-based electrochemical hybridization assay was applied to the detection of methylated cytosine of DNA using the products obtained after treatment with bisulfite followed by polymerase chain reaction (PCR), where unmethylated cytosine is converted to thymine and methylated one to cytosine. Twenty-meric DNA probes for the methylated (cytosine) and unmethylated (thymine) types of the part of the promoter region of cyclin D-dependent protein kinase inhibitor, p16, gene (p16(Ink4a)) were used to be immobilized on the electrochemical array (ECA) chip. Using 1 microL of 10 ng/microL of methylated sample obtained from the methylation-specific PCR of methylated genome containing 10-times excess of unmethylated one, the methylated PCR sample could be detected by the identical electrochemical signals from the two DNA probes under the settled optimum hybridization conditions.

Abstract
Surface plasmon resonance imaging (SPRI) sensors allow the characterization of a metal/dielectric interface. Providing proper biochemical functionalization and spatial structuration of the functionalized surface, an optical biochip system--label free and real time--can be achieved. We study the impact of the different physical parameters on the quality of the measurements. Such a SPRI system has a great sensitivity to small variations of the physical parameters (layer optical index, thickness, etc.) occurring at the sensor surface. Precision and reliability of the measurements are provided by a multidimensional approach (4D i.e. spatial coordinates x-y, time t, angle of incidence theta) allowing multiple self-calibration procedures. Such apparatus has already been successfully applied in genomics and proteomics, studying DNA:DNA and oligosaccharide:protein interactions. In this article, we illustrate the advantages of the SPRI setup applied to the detection of gene mutations, using as a model the genetic disease Cystic Fibrosis. The results demonstrate that the system is able to monitor and analyse the interaction under investigation, allowing the diagnosis of genetic single nucleotide polymorphisms by exploiting only a part of the multidimensional potential (x, y, t, theta).
