This review addresses this gap by critically analysing recent literature on pharmaceutical sorption to micro(nano)plastics in environmental samples or under simulated natural conditions. Key findings underscore the nature of these interactions, influenced by factors such as microplastics’ type, surface area, and biofouling. However, the scarcity of field studies and persistent analytical challenges (including sampling, extraction, and detection limitations), hinder a comprehensive understanding of these processes in real scenarios. Future efforts should prioritise the development of standardised methodologies, advanced analytical techniques, and expanded field-based monitoring to comprehensively assess the environmental and human health risks associated with pharmaceutical-microplastic interactions.

Multiplexed detection, seeking either the simultaneous assessment of multiple analytes in the same experiment or the multi-detection of a single analyte in a complex sample matrix replete of interfering species, has gained, in recent years, a noteworthy interest amidst the analytical community. Evolving from early conventional techniques, multiplexed detection has been able, to deliver reliable and efficient analysis in fields as different as clinical, pharmaceutical, food and environmental analysis. The research on nanomaterials, in particular on photoluminescent quantum dots (QDs), has paved the way for the implementation of innovative and flexible multiplexed assays since their remarkable optical properties and tailored reactivity could be arranged in many configurations, combining different fluorophores and molecular recognition elements and providing the means for the establishment of definite reaction pathways and detection methods. From this particular study it concludes that, the development of QDs -based multiplexed detection techniques, examine the distinct roles they could play at the sensing platform, either alone or combined with other materials, and discuss the emerging developments and trends of QDs based nanosensors for the real-time detection of heavy metal ions.

This review aims to provide an overview on this methodological complexity and to identify key parameters and their potential influence on the results and method interpretation. Parameters of all available studies were summarized in a complex table. The amount and concentration of oxidation reagents, the reaction time, temperature and pH value during oxidation, the time of internal standard addition, and the suite of analyzed oxidation products were identified as key factors affecting oxidation efficiency, nature of reaction products, and completeness of precursor assessment. The current complexity of TOP assay approaches demonstrates the need for further method harmonization and standardization, which should include measures to ensure and assess the completeness of precursor oxidation. A further understanding of the chemical reactions during the TOP assay and the inclusion of additional oxidation endpoints were identified as research needs for the future.

MMIPs are easily separated from a variety of complicated matrices and have a high adsorption capability. They play an essential role in the efficient extraction of various analytes from a variety of matrices, including water, soil, food and its derivatives, plant extraction, fruits and vegetables, and various biological samples.

Surface runoff from their widespread use pollutes water and soil. Pesticides deplete beneficial insect populations, upset ecological equilibrium, and contaminate food chains, posing health concerns through bioaccumulation and biomagnification. Moreover, heavy metals from industry, mining, and inappropriate waste disposal are persistent, harmful environmental pollutants. Lead, mercury, cadmium, and arsenic in soils and sediments pollute water supplies and endanger aquatic life, wildlife, and humans. Heavy metal exposure can cause neurological issues, reproductive abnormalities, and cancer, making cleanup necessary. Also, industrial activities, wastewater discharge, and agricultural runoff produce phenolic compounds, another harmful environmental contaminant. Bisphenol A, phenol, and chlorophenols poison aquatic species, limit plant photosynthesis, and alter microbial populations. Additionally, phenolic chemicals can stay in the environment for lengthy durations, causing long-term ecological damage and health concerns from tainted drinking water and food. As a result, environmental monitoring is becoming increasingly important for sensitively detecting and quantifying pesticides, phenolic compounds, and heavy metals. Electrochemical sensors and modification materials are prepared for specific pollutant detection, providing selectivity and sensitivity, thus enabling the detection of the target molecule down to the nanomolar or even picomolar range. In this respect, ordered mesoporous carbon (OMC) materials attract attention in electrochemical sensing applications due to their numerous advantages. OMCs are promising for catalysis and sensing applications due to their well-ordered pore structure, high specific surface area, and tunable pore sizes in the mesopore range. The unique properties of these materials could open a new approach to studying the electrochemical determination of other environmental pollutants.
