“…Pesticide residues pose a risk to public health; and thus, the EU and other countries in the world have established a legislative framework to control these chemicals in foodstuffs [132], and sensitive analytical methods are needed to control their presence in both raw materials and processed foods. The number of papers dealing with the analysis of pesticides in food is extensive, and immunochemical techniques have been regularly applied to their control during decades [133][134][135].…”

“…It is mainly based on the construction of the sandwich structure. The solid-phase antibody and the labeled antibody on the substrate combine with the antigen to form a sandwich complex of "solid-phase antibody-antigen-labeled antibody," which is used for immune analysis by recognizing the SERS signal of the marker molecule [173]. Antibodies are employed as the capture agent to specifically extract and concentrate targets from complex matrices ahead of SERS test.…”

Surface-enhanced Raman spectroscopy is an alternative detection tool for monitoring food security. However, there is still a lack of a conclusion of SERS detection with respect to pesticides and real sample analysis, and the summary of intelligent algorithms in SERS is also a blank. In this review, a comprehensive report of pesticides detection using SERS technology is given. The SERS detection characteristics of different types of pesticides and the influence of substrate on inspection are discussed and compared by the typical ways of classification. The key points, including the progress in real sample analysis and Raman data processing methods with intelligent algorithm, are highlighted. Lastly, major challenges and future research trends of SERS analysis of pesticide residue are also addressed. SERS has been proven to be a powerful technique for rapid test of residue pesticides in complex food matrices, but there still is a tremendous development space for future research.

“…Immunosensors combining immunochemical reactions based on the antibody (Ab)-antigen (Ag) recognition with an appropriate electrochemical transducer provide significant advantages for bioanalysis, including cost-effectiveness, low reagent and sample volume, portability, high-specificity and sensitivity, and high-throughput analysis [ 76 ]. Immunosensors have applications in various fields of analysis, such as clinical medicine [ 77 , 78 ], environmental pollutant evaluation [ 79 , 80 , 81 ], food inspection [ 82 , 83 ], and pathogenic microorganism detection [ 84 , 85 ].…”

MXenes are recently developed 2D layered nanomaterials that provide unique capabilities for bioanalytical applications. These include high metallic conductivity, large surface area, hydrophilicity, high ion transport properties, low diffusion barrier, biocompatibility, and ease of surface functionalization. MXenes are composed of transition metal carbides, nitrides, or carbonitrides and have a general formula Mn+1Xn, where M is an early transition metal while X is carbon and/or nitrogen. Due to their unique features, MXenes have attracted significant attention in fields such as clean energy production, electronics, fuel cells, supercapacitors, and catalysis. Their composition and layered structure make MXenes attractive for biosensing applications. The high conductivity allows these materials to be used in the design of electrochemical biosensors and the multilayered configuration makes them an efficient immobilization matrix for the retention of activity of the immobilized biomolecules. These properties are applicable to many biosensing systems and applications. This review describes the progress made on the use and application of MXenes in the development of electrochemical and optical biosensors and highlights future needs and opportunities in this field. In particular, opportunities for developing wearable sensors and systems with integrated biomolecule recognition are highlighted.
