Abstract:
Since the fabrication of the first electrochemical biosensor by Leland C. Clark in 1956, various labeled and label-free sensors have been reported for the detection of biomolecules. Labels such as nanoparticles, enzymes, Quantum dots, redox-active molecules, low dimensional carbon materials, etc. have been employed for the detection of biomolecules. Because of the absence of cross-reaction and highly selective detection, labeled biosensors are advantageous and preferred over label-free biosensors. The biosensors with labels depend mainly on optical, magnetic, electrical, and mechanical princip

Abstract:
AbstractDNA and aptasensors are widely used for fast and reliable detection of disease biomarkers, pharmaceuticals, toxins, metabolites and other species necessary for biomedical diagnostics. In the overview, the concept of spatially distributed redox mediators is considered with particular emphasis to the signal generation and biospecific layer assembling. The application of non-conductive polymers bearing redox labels, supramolecular carriers with attached DNA aptamers and redox active dyes and E-sensor concept are considered as examples of the approach announced.

Abstract:
This review shows recent trends in the use of nanoparticles as labels for electrochemical immunosensing applications. Some general considerations on the principles of both the direct detection based on redox properties and indirect detection through electrocatalytic properties, before focusing on the applications for mainly proteins detection, are given. Emerging use as blocking tags in nanochannels-based immunosensing systems is also covered in this review. Finally, aspects related to the analytical performance of the developed devices together with prospects for future improvements and appli

Abstract:
MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression and have emerged as critical biomarkers in various diseases, including cancer. Their stability in bodily fluids and role as oncogenes or tumor suppressors make them attractive targets for non-invasive diagnostics. However, conventional detection methods, such as Northern blotting, RT-PCR, and microarrays, are limited by low sensitivity, lengthy protocols, and limited specificity. Electrochemical biosensors offer a promising alternative, providing high sensitivity, rapid response times, portability, and cost-effectivene

Abstract:
Nanocatalysts are a promising alternative to natural enzymes as the signal labels of electrochemical biosensors. However, the surface modification of nanocatalysts and sensor electrodes with recognition elements and blockers may form a barrier to direct electron transfer, thus limiting the application of nanocatalysts in electrochemical immunoassays. Electron mediators can accelerate the electron transfer between nanocatalysts and electrodes. Nevertheless, it is hard to simultaneously achieve fast electron exchange between nanocatalysts and redox mediators as well as substrates. This work pres

Abstract:
In recent years, the need for simple, fast, and economical detection of food and environmental contaminants, and the necessity to monitor biomarkers of different diseases have considerably accelerated the development of biosensor technology. However, designing biosensors capable of simultaneous determination of two or more analytes in a single measurement, for example on a single working electrode in single solution, is still a great challenge. On the other hand, such analysis offers many advantages compared to single analyte tests, such as cost per test, labor, throughput, and convenience. Be

Abstract:
Direct electron transfer (DET) between an electrode and redox labels is feasible in electrochemical biosensors using small aptamer–aptamer sandwiches; however, its application is limited in biosensors that rely on larger antibody–antibody sandwiches. The development of sandwich-type biosensors utilizing DET is challenged by the scarcity of aptamer–aptamer sandwich pairs with high affinity in complex biological samples. In this presentation, we introduce an electrochemical biosensor using an antibody–aptamer hybrid sandwich for detecting thrombin in human serum. The biosensor enables rapid DET

BACKGROUND: The cysteine (Cys) proteome includes 214.000 Cys with thiol and other forms. Of these, only a relatively small subset functions in cell signalling. Redox-active Cys are more susceptible to oxidation, and their oxidized form is more susceptible to reduction. Specific proteomic techniques are required to identify these modifications and to study their regulation in different cell processes that are collectively known as redox proteomics. Thus, it is of interest to be able to identify both the proteins and the cysteine residues affected, and to quantify the extent of the modification

However, changes in cellular redox alone are insufficient to fully characterize cancer metabolism and predict invasive potential. We demonstrate that label-free MPM measurements of TPEF-derive

Oxidation-labile protecting groups offer a means of releasing functional groups under essentially neutral conditions which is useful when hydrolytic deprotection is not tolerated and silyl protecting groups are unsuitable. In particular, a CH<sub>2</sub> group that links a functional group to an electron-rich aromatic ring is prone to oxidation giving a hemiacetal, which is unstable with respect to aldehyde formation, and release of the functional group.
