“…Wang et al developed a label-free aptasensor based on an electrochemiluminescent (ECL) strategy with ZnS–CdS NP-decorated molybdenum disulfide (MoS 2 , a 2D nanomaterial [ 105 ]) nanocomposite for CEA detection [ 106 ]. The GCE was firstly modified with layered MoS 2 as an electrode matrix, and then ZnS–CdS NPs were electrodeposited directly onto MoS 2 /GCE.…”

This comprehensive review paper describes recent advances made in the field of electrochemical nanobiosensors for the detection of breast cancer (BC) biomarkers such as specific genes, microRNA, proteins, circulating tumor cells, BC cell lines, and exosomes or exosome-derived biomarkers. Besides the description of key functional characteristics of electrochemical nanobiosensors, the reader can find basic statistic information about BC incidence and mortality, breast pathology, and current clinically used BC biomarkers. The final part of the review is focused on challenges that need to be addressed in order to apply electrochemical nanobiosensors in a clinical practice.

“…Exfoliation of the bulk substances into a few layers mostly conserves their characteristics and also leads to additional features due to restriction impacts. These materials have sparked numerous interest due to their unique physical characteristics and special applications (Jayabal et al 2017;Chhowalla et al 2013;Arshad et al 2019). In opposition to graphene possessing a zero bandgap, transition metal dichalcogenides have a bandgap comparable to Si or GaAs and offer an interesting ability for reducing the size of the technology and semiconductor to the nanoscale.…”

The world is currently facing critical water and energy issues due to the growing population and industrialization, calling for methods to obtain potable water, e.g., by photocatalysis, and to convert solar energy into fuels such as chemical or electrical energy, then storing this energy. Energy storage has been recently improved by using electrochemical capacitors and ion batteries. Research is actually focusing on the synthesis of materials and hybrids displaying improved electronic, physiochemical, electrical, and optical properties. Here, we review molybdenum disulfide (MoS2) materials and hybrids with focus on synthesis, electronic structure and properties, calculations of state, bandgap and charge density profiles, and applications in energy storage and water remediation.

“…Furthermore, the MoS 2 possesses an ultrathin plane structure of atomic thickness making it sensitive to the surrounding environment [26]; thus, an interaction with a target biomolecule can affect its whole thickness. These properties have been explored for design of FET biosensing platform [27] as well as electrochemical biosensors [28]. Additionally, it was demonstrated that MoS 2 has a high affinity towards ssDNA oligonucleotides and is able to spontaneously adsorb them via van der Waals interactions between nucleobases and the basal plane of MoS 2 nano-sheets [29].…”

Self-Assembled MoS2/ssDNA Nanostructures for the Capacitive Aptasensing of Acetamiprid Insecticide

The aim of this work is to detect acetamiprid using electrochemical capacitance spectroscopy, which is widely used as a pesticide in agriculture and is harmful to humans. We have designed aptasensing platform based on the adsorption of a DNA aptamer on lipoic acid-modified MoS2 nano-sheets. The biosensor takes advantage of the high affinity of single-stranded DNA sequences to MoS2 nano-sheets. The stability of DNA on MoS2 nano-sheets is assured by covalent attachment to lipoic acid that forms self-assembled layer on MoS2 surface. The biosensor exhibits excellent capacitance performances owing to its large effective surface area making it interesting material for capacitive transduction system. The impedance-derived capacitance varies with the increasing concentrations of acetamiprid that can be attributed to the aptamer desorption from the MoS2 nanosheets facilitating ion diffusion into MoS2 interlayers. The developed device showed high analytical performances for acetamiprid detection on electrochemical impedance spectroscopy EIS- derived capacitance variation and high selectivity toward the target in presence of other pesticides. Real sample analysis of food stuff such as tomatoes is demonstrated which open the way to their use for monitoring of food contaminants by tailoring the aptamer.
