During the last years, a lot of efforts have been put into developing novel sensors and biosensors systems for monitoring the occurrence of emerging pollutants in the environment. These analyses are often challenging because of the variety of physico-chemical properties of these substances, the extremely diluted concentrations at which they can be found, and the intrinsic complexity of environmental matrices. In order to improve the (bio)sensors' performance, preconcentration/pretreatment techniques may be implemented. The automatization of these systems results in an autonomous, straight-forward alternative to classic chromatography-based methods, which in addition can operate remotely with real-time or pseud-real-time measurements. The present review offers an overview about these potentially automatable extraction techniques and provides some references about their recent use in environmental sensing and biosensors.

Hypochlorous acid (HClO) is a well-known inflammatory signaling molecule, while lipid droplets (LDs) are dynamic organelles closely related to inflammation. Using organic small-molecule fluorescence imaging technology to target LDs for precise monitoring of HClO is one of the most effective methods for diagnosing inflammation-related diseases. A thorough investigation of how probes detect biological markers and the influencing factors can aid in the design of probe molecules, the selection of high-performance tools, and the accuracy of disease detection.

In recent years, nanozyme-based analytics have become popular. Among these, laccase nanozyme-based colorimetric sensors have emerged as simple and rapid colorimetric detection methods for various analytes, effectively addressing natural enzymes' stability and high-cost limitations. Laccase nanozymes are nanomaterials that exhibit inherent laccase enzyme-like activity.

Dimethoate (DIM) is one of the most extensively applied organophosphorus pesticides (OPs), which is used to boost farm productivity due to its high insecticidal efficacy. However, the excessive use of DIM can result in the extensive contamination of soil, groundwater and food. Monitoring of DIM in environmental and food samples is crucial in view of its potential health risks and environmental hazards from excessive residues.

Background: Atrazine (ATZ), a pesticide that poses serious health problems, is observed in the environment, thereby prompting its periodic monitoring and control using functional biosensors. However, established methods for ATZ detection have limited applicability. Two-dimensional (2D) metal azolate frameworks (MAF) have a higher surface area per unit volume and provide easier access to active sites.
