“…For example, the affinity of the aptamers for their targets can be affected, decreasing sensitivity and specificity, causing false positives or negatives, depending on the complexity of the matrix, or using aptasensors that recognize multiple analytes. The high affinity of aptamers for their target correlates with their detection at low concentrations [ 4 , 5 ].…”

“…For example, it has been reported the degradation of nucleic acids by nucleases in real environments. New strategies to improve the stability of the aptamers through modified nucleotides, by including chemical groups (2′- O -methoxy or 2′-fluoro or motifs) to replace 2′OH moieties, or by the addition of hairpin structures to the 5′ or 3′ ends have been proposed [ 5 , 6 ]. In addition, the backbone of the aptamers, which are phosphodiester bonds, can be substituted by residues of phosphorothioate and boranophosphate or nucleic acid peptides [ 6 ].…”

“…The relevance of mitigating the contamination caused by EPs is based on their characteristics related to bioavailability, mobilization, transformation, and persistence in water, sediments, and soil [ 5 ]. Moreover, EPs can be introduced to the food chain through different pathways, such as irrigation with contaminated water and plant uptake [ 6 ].…”

The synergistic potentialities of innovative materials that include aptamers have opened new paradigms in biosensing platforms for high-throughput monitoring systems. The available nucleobase functional moieties in aptamers offer exclusive features for bioanalytical sensing applications. In this context, compared to various in-practice biological recognition elements, the utilization of aptamers in detection platforms results in an extensive range of advantages in terms of design flexibility, stability, and sensitivity, among other attributes. Thus, the utilization of aptamers-based biosensing platforms is extensively anticipated to meet unaddressed challenges of various in-practice and standard analytical and sensing techniques. Furthermore, the superior characteristics of aptasensors have led to their applicability in the detection of harmful pollutants present in ever-increasing concentrations in different environmental matrices and water bodies, seeking to achieve simple and real-time monitoring. Considering the above-mentioned critiques and notable functional attributes of aptamers, herein, we reviewed aptamers as a fascinating interface to design, develop, and deploy a new generation of monitoring systems to aid modern bioanalytical sensing applications. Moreover, this review aims to summarize the most recent advances in the development and application of aptasensors for the detection of various emerging pollutants (EPs), e.g., pharmaceutical, and personal care products (PPCPs), endocrine-disrupting chemicals (EDCs), pesticides and other agricultural-related compounds, and toxic heavy elements. In addition, the limitations and current challenges are also reviewed, considering the technical constraints and complexity of the environmental samples.

“…For example, PFASs containing aliphatic carbon backbones with the side chain hydrogens substituted by fluorines are used in consumer goods such as surfactants, firefighting foams, alkaline cleaners, carpets, non-sticky pans, room polishers, shampoos, fume resistants, photo films, semiconductors, food packaging, pesticides, denture cleaners, and masks [ 3 ]. In principle, ECs may adversely affect ecological conditions and human health; however, as they may undergo various transformations (e.g., degradation processes) when introduced into the environment, it is not easy to determine their overall impact on living organisms and research in this area is still being conducted [ 1 , 4 , 5 ]. Many reports related to the analysis of different types of environmental samples (e.g., surface water and groundwater, soil) have confirmed the increasing presence of emerging contaminants and products of their transformations [ 6 ].…”

The Application of Polymer Inclusion Membranes for the Removal of Emerging Contaminants and Synthetic Dyes from Aqueous Solutions—A Mini Review

2023

Pollution of the environment, including water resources, is currently one of the greatest challenges due to emerging new contaminants of anthropogenic origin. Of particular concern are emerging organic pollutants such as pharmaceuticals, endocrine disruptors, and pesticides, but also other industrial pollutants, for example, synthetic dyes. The growing demand for environmentally friendly and economical methods of removing emerging contaminants and synthetic dyes from wastewater resulted in increased interest in the possibility of using techniques based on the application of polymer inclusion membranes (PIMs) for this purpose. PIM-based techniques are promising methods for eliminating emerging contaminants and synthetic dyes from aqueous solutions, including wastewater, due to high efficiency, membranes versatility, ease/low cost of preparation, and high selectivity. This review describes the latest developments related to the removal of various emerging contaminants and synthetic dyes from aqueous solutions using PIMs over the past few years, with particular emphasis on research aimed at increasing the effectiveness and selectivity of PIMs, which may contribute to wider use of these methods in the future.

“…Aqueous phase photolysis, biodegradation, and sorption into the soil phase are often considered as primary fate and transport pathways of ECs in the aquatic ecosystem. 1–3 However, there are numerous soft interfaces with which aquatic pollutants can interact. These include the water surface, polymeric substrates of particulate matters ( e.g.…”
