“…Recently, various novel nanomaterials were synthesized and applied in the development of sensitive and stable biosensors. Among them, two-dimensional materials such as transition-metal dichalcogenides (TMDs) and MXenes (few-atom-thick layers of transition metal carbides, nitrides, or carbonitrides) received much attention because of their unique physical, chemical, and electrical properties such as high conductivity, high ion transport efficiency, large activated surface area, and low diffusion barrier [65,66]. Not all TMDs are superior to other nanomaterials including carbon nanomaterials in general.…”

Biosensors are very important for detecting target molecules with high accuracy, selectivity, and signal-to-noise ratio. Biosensors developed using biomolecules such as enzymes or nucleic acids which were used as the probes for detecting the target molecules were studied widely due to their advantages. For example, enzymes can react with certain molecules rapidly and selectively, and nucleic acids can bind to their complementary sequences delicately in nanoscale. In addition, biomolecules can be immobilized and conjugated with other materials by surface modification through the recombination or introduction of chemical linkers. However, these biosensors have some essential limitations because of instability and low signal strength derived from the detector biomolecules. Functional nanomaterials offer a solution to overcome these limitations of biomolecules by hybridization with or replacing the biomolecules. Functional nanomaterials can give advantages for developing biosensors including the increment of electrochemical signals, retention of activity of biomolecules for a long-term period, and extension of investigating tools by using its unique plasmonic and optical properties. Up to now, various nanomaterials were synthesized and reported, from widely used gold nanoparticles to novel nanomaterials that are either carbon-based or transition-metal dichalcogenide (TMD)-based. These nanomaterials were utilized either by themselves or by hybridization with other nanomaterials to develop highly sensitive biosensors. In this review, highly sensitive biosensors developed from excellent novel nanomaterials are discussed through a selective overview of recently reported researches. We also suggest creative breakthroughs for the development of next-generation biosensors using the novel nanomaterials for detecting harmful target molecules with high sensitivity.

“…Several breakthroughs in MXene synthesis and MXene-nanocomposite preparation resulted in various elemental compositions and surface functional tunabilities (Khazaei et al, 2019). During the last few years, MXenes have played an ever important role in terms of both crystalline and composition varieties for catalysis (Zhang et al, 2018;Benchakar et al, 2019;Li and Wu, 2019;Sun et al, 2019), environmental applications (Rasool et al, 2019), development of Li batteries (Ostadhossein et al, 2019;, and (bio)sensors (Kalambate et al, 2019;Lorencova et al, 2019;Mohammadniaei et al, 2019;Wu Q. et al, 2019;Gajdosova et al, 2020;Szuplewska et al, 2020).…”

Recently, composites of MXenes and two-dimensional transition metal dichalcogenides have emerged as promising materials for energy storage applications. In this study, W2C/WS2 alloy nanoflowers (NFs) were prepared by a facile hydrothermal method. The alloy NFs showed a particle size of 200 nm–1 μm, which could be controlled. The electrochemical performance of the as-prepared alloy NFs was investigated to evaluate their potential for application as lithium-ion battery (LIB) anodes. The incorporation of W2C in the WS2 NFs improved their electronic properties. Among them, the W2C/WS2_4h NF electrode showed the best electrochemical performance with an initial discharge capacity of 1040 mAh g−1 and excellent cyclability corresponding to a reversible capacity of 500 mAh g−1 after 100 cycles compared to that of the pure WS2 NF electrode. Therefore, the incorporation of W2C is a promising approach to improve the performance of LIB anode materials.
