The importance of nanotechnology is increasing every day in different fields and, especially, the application nanomaterials has attracted considerable attention food safety. Among nanomaterials, MXenes, which are two-dimensional (2D) transition metal-based layered materials made nitrides and carbides, have revolutionized various as a cutting-edge scientific discovery nanotechnology. These been widely used structure biosensors sensors due to their excellent metallic conductivity, mechanical stability, optical absorbance, good redox capability, higher heterogeneous electron transfer rate. In particular, MXenes nanozymes highlighted high performance great extent biosensor domains. growing interest these attributed specific physicochemical features. key enzymatic features include activities similar oxidase, peroxidase, catalase, superoxide dismutase. this review, initially, several common synthesis methods presented, emphasizing significant role constructing efficient sensors. Subsequently, applications MXene safety analysis delved into, including detection bacteria, mycotoxins, antibiotic residues, pesticide along with electrochemical biosensors. addition, gap, limitation, future perspective novel highlighted.

Gold nanorods (AuNRs), as versatile sensing materials, have wide analytical applications due to their unique optical properties. Cetyltrimethylammonium bromide (C16TAB), a conventional reagent in AuNR synthesis, also often acts stabilizer of AuNRs applications. However, C16TAB-stabilized undergo severe spontaneous aggregation and etching under extreme pH conditions, greatly limiting Herein, we accidentally discovered that octadecyl trimethylammonium (C18TAB), rarely used surfactant for AuNRs, has substantially higher stabilizing ability than C16TAB preventing which enables C18TAB-stabilized superior platform, demonstrating 100-fold sensitivity detection model analytes. The excellent stability can be attributed the coverage density on gold surface, evidenced by red-shifted longitudinal band (5 nm), is tuned metal surface refraction index. experimental results show keep monodispersed unchanged properties at very acidic alkaline conditions with low concentration (0.05 mM). Moreover, prevent system maintain plasmon band, therefore decreasing intensity noise signal. Benefiting from these findings, established reliable ultrasensitive platform achieved biomarker p-aminophenol (pAP), visual limit 8 nM. This represents least improvement over existing method using AuNRs. were successfully applied detect pAP urine samples satisfactory recovery rates 99.84–114.91%, further validating its reliability practical In summary, provide powerful tool trace-level chemo- biosensing.
