“…Figure 8 depicts the synthesis procedure, and SERS spectra of the materials along with the reaction mechanism. [104] The MXene-Au hybrid structures, in a similar manner, were able to detect MB and CV dyes at low concentrations below 10 −8 m. According to reports, Au nanoparticles loaded with Ti 3 C 2 T x MXene sheets on paper substrates have good sensitivity, stability, and reproducibility with an EF of 3.7 × 10 5 at concentrations of 10 −9 m R6G. [112] In addition, the Au-MXene substrate por-trayed the sensitive and noninvasive glucose detection from diabetic tears (in the linear range 1-50 m) with LOD of 0.39 m. Furthermore, Yang and researchers demonstrated that MXene placed on a 3D transferable microfluidic SERS substrate could robustly sense gases, namely, 2,4-dinitrotoluene (DNT), indole, and odoriferous benzaldehyde with a LOD in the range 10-50 ppb.…”

“…Au-based nanostructures are highly favored for biosensing drugs, environmental monitoring, imaging, and SERS-related applications, ascribed to their optical features linked to a powerful LSPR and stable nature. [104][105][106] By taking into account the benefits of the electrostatic interactions, Xie et al reported the SERS substrate fabrication utilizing uniformly decorated Au nanorods (NRs) on Ti 3 C 2 MXene. [107] When 532 and 633 nm lasers were used as excitation sources, the MXene/Au NRs SERS substrate displayed good sensitivity for the detection of R6G, CV, and Malachite Green (MG) with LODs of 1 × 10 −12 , 1 × 10 −12 , and 1 × 10 −10 m, respectively (Figure 7).…”

Surface‐enhanced enhanced Raman spectroscopy (SERS) has emerged as a powerful analytical technique for ultrasensitive and label‐free detection of chemical species, with numerous applications in various fields. Recently, 2D MXenes, have evoked substantial intrigue as promising substrates for SERS. Hence, a comprehensive understanding of the developments in the Raman effect and the mechanisms involved in SERS is highly crucial. The review reflects the advances, working principle, and dual mechanisms, including SERS's electromagnetic and chemical mechanisms. Noble metal nanostructures are highly prioritized as SERS substrates owing to their excellent sensitivity. However, due to certain disadvantages that they pose, metal‐free SERS substrates with exceptional tunable properties are extensively researched in the current days. The combination of 2D MXenes and nanostructures can be effective in producing enhanced SERS signals. SERS performance of different MXene‐based materials is emphasized. The performance of this combination is credited to their large surface‐to‐volume ratio, good electrical conductivity, and surface‐terminated functionalities. The recent advancements in MXenes and MXenes‐based heterostructures driven SERS sensing concerning the structural design of the material, its performance, and the mechanisms are studied. Finally, a detailed conclusion is provided with the challenges and future perspectives for designing 2D materials for efficient SERS sensors.

“…As an organophosphorus insecticide and acaricide, isocarbophos (ICP) can induce several acute toxicities and are carcinogenic to humans. Zhi et al [ 111 ] developed a Ti 3 C 2 MXene@Au sol support ICP aptamer probe using the catalytic activity of the sol to reduce mandelic acid-chloroauric acid (MA-HAuCl 4 ) for a dual-mode measurement of the ICP concentration in farmland wastewater with high stability, reproducibility, and specificity.…”

MXene is a two-dimensional (2D) nanomaterial that exhibits several superior properties suitable for fabricating biosensors. Likewise, the nucleic acid (NA) in oligomerization forms possesses highly specific biorecognition ability and other features amenable to biosensing. Hence the combined use of MXene and NA is becoming increasingly common in biosensor design and development. In this review, MXene- and NA-based biosensors are discussed in terms of their sensing mechanisms and fabrication details. MXenes are introduced from their definition and synthesis process to their characterization followed by their use in NA-mediated biosensor fabrication. The emphasis is placed on the detection of various targets relevant to agricultural and food systems, including microbial pathogens, chemical toxicants, heavy metals, organic pollutants, etc. Finally, current challenges and future perspectives are presented with an eye toward the development of advanced biosensors with improved detection performance.

“…Peng et al170 prepared Ti 3 C 2 MXene and studied SERS properties based on the "coupled resonance" effect, an effective strategy that considers charge transfer resonance for semiconductor-based substrates developed to optimize the SERS sensitivity. Zhi et al171 prepared Ti 3 C 2 MXene nanosheets for the first time with the microwave irradiation method for the aptamer SERS quantitative assay platform for isocarbophos. They constructed a new fast, sensitive, and accurate SERS/RRS amplification platform with MXene material.…”

MXenes are the new members in the family of two-dimensional (2D) layered materials composed of transitional metal carbides, nitrides, or carbonitrides. Among all other MXenes, Ti3C2T x MXene is the most studied one due to the exceptional properties that make it suitable for various applications, including optoelectronics. Ti3C2T x MXene can be fabricated and processed in a variety of scalable and cost-effective ways. MXenes are solution-processable materials that can be deposited by spin, spray, or dip coating, painting, or printing. They exhibit excellent optical transparency, high metallic conductivity, efficient photothermal conversion, plasmonic behavior, and tunability of the optical response over traditional 2D materials. These features have led to a fast evolution of this material with many explorations of its applications in the field of optoelectronics. This short review summarizes the recent updates on the synthesis, optical, as well as electronic properties, and the various optoelectronic applications of Ti3C2T x MXene in the materials point of view. The challenges to be overcome for their successful integration into the optoelectronics domain and opportunities for future explorations are also discussed.
