Abstract Sustainable cultivation and safe agricultural production are needed to ensure the safety of all living organisms ecosystems. Most foods currently contain unacceptable levels pesticide residues. In an attempt pest control high crop yields, farmers spray a large number pesticides in quantities that exceed limits for crops. Pesticide residues highly toxic humans, causing severe even deadly diseases. Traditional analytical strategies laboratory detection often limited because they time‐consuming require trained personnel, which makes them very costly. Hence, accurate, rapid, on‐site analysis is drawing increasing attention food reasons. Therefore, or point‐of‐care (POC) has become approach paramount importance. Recently, various portable technologies, such as colorimetric, fluorescence, electrochemical, surface plasmon resonance, chemiluminescence, phosphorescence, microfluidic, surface‐enhanced Raman scattering techniques, have been designed monitoring vegetables fruits. These devices demonstrated great power preclinical settings. This review highlights emerging insights novel advances devices, POC sensing approaches foods. However, greater rigor design pesticide‐detection essential. The demand rapid hazardous components prompted timely opportunity summarize recent developments progress evaluate safety.

A review of the current status direct and indirect potable water reuse (DPR/IPR) implementation has been conducted, focusing on regulatory practical aspects with reference to most recent published literature. The encompasses (a) principal contaminant types, their required removal methods by which concentration is monitored, (b) approaches stipulations in assessing/ratifying treatment schemes maintaining treated quality, (c) existing full-scale installations. Analytical discussed include established in-line monitoring tools, such as turbidity measurement, more polymerase chain reaction (PCR)-based assay for microbial detection. key risk assessment tools quantitative (QMRA) safety plans (WSPs) are considered relation use selecting/ratifying schemes, components from 40 IPR/DPR installations summarised. Five specific detail. reveals:Whilst there a number ongoing projects where RO not used because challenge imposed disposal concentrate, prevalence sequential RO-UV combination implies importance quantifying impact process upsets these unit operations.

Monitoring phenolic compounds is critical in the environmental, food, and medical sectors. Among many recent advanced detection platforms, laccase-based biosensing platforms gave very rapid, effective, online, situ sensing of compounds. In biosensors, laccase immobilization techniques have a vital role. However, detailing advancements employed biosensors lacking literature. Thus, this review, we assessed how nano-immobilization shaped platforms. We discussed novel developments such as entrapment, adsorption, cross-linking, covalent over new nanocomposites biosensors. made comprehensive assessment based on current literature for future perspectives nano-immobilized found important key areas toward which biosensor research seems to be heading. These include 1. A focus development multi-layer electrode surface, 2. The need utilize more routes, they change specificity compounds, 3. advancement polymeric matrices with electroconductive properties, 4. entrapment like biomineralization using molecules. provided detailed account their feasibility highly specific industrial, medicinal, environmental applications.
