Cellulose Nanofiber Films with Gold Nanoparticles Electrostatically Adsorbed for Facile Surface-Enhanced Raman Scattering Detection

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: April 24, 2024

Cellulose nanofiber (CNF) holds great promise in applications such as surface-enhanced Raman scattering (SERS), catalysis, esthesia, and detection. This study aimed to build novel CNF-based SERS substrates through a facile synthetic method. Citrate-reduced gold nanoparticles (AuNPs) were adsorbed on the cationized CNF surface due electrostatic interactions, uniform AuNPs@(2,3-epoxypropyl trimethylammonium chloride)EPTMAC@CNF flexible prepared by simple vacuum-assisted filtration The probe molecule methylene blue was chosen assess performance of substrate with sensitivity up 10-9 M, superior signal reproducibility (relative standard deviation (RSD) = 4.67%), storage stability (more than 30 days). Tensile strength tests indicated that films had good mechanical properties. In addition, can easily capture visually identify microplastics water. These results demonstrate potential application flexible, self-assembled AuNPs@EPTMAC@CNF for prompt sensitive detection trace substances.

Microplastics are pollutants formed from fragmented plastics and also industrially manufactured for personal care cosmetic products. They range 1 µm to 5 mm ubiquitous in the environment due their tiny size, lightweight, wide applications. Ecotoxicological studies have shown that they can induce multiple harmful effects on exposed organisms humans. Wastewater treatment plants (WWTPs) drawn interest of researchers regulatory bodies worldwide as a point source microplastics discharge environment. In absence standardized methodology, microplastic monitoring WWTPs has been marked by distinct variations sample processing analytical procedures which limit comparison results. This review provides detailed analysis methods patterns, analytical, size characterization, quantification WWTPs. According procedural steps extraction reported reviewed studies, 12 patterns three categories approaches (single, dual, multiple) were identified. quantified using gravimetry method, mass sub-sample method (based extrapolation) with latter being most applied technique. Microplastic characterization accomplished two main methods: sieve-based technique computing-based

Published: Nov. 8, 2024

Due to their widespread distribution, microplastics (MPs) are endangering the soil ecological environment system, causing water pollution and altering soil’s physicochemical microbiological features. Because of its unique pore structure strong stability, biochar is widely used as an adsorbent. However, effects MP–biochar interactions in still unclear. This review outlines application mechanism adsorbent a for removal MPs. Also, serves remediation material MPs soils it mitigates adverse on properties, enzyme activities microbial community. It was found that woody had highest yield more effective adsorbing Further research should focus combined MPs, environmental risks biochar, modification MP-removal technologies, characterization MP contamination other pollutants, transportation

Cationic Nanoparticle Networks (CNNs) with Remarkably Efficient, Simultaneous Adsorption of Microplastics and PFAS

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

Of the past decade, micro/nanoplastics (MP/NP) and per- polyfluoroalkyl substances (PFAS) have become two of most pervasive persistent organic pollutants leading to significant accumulation within waterways. Various sorbent materials been evaluated for PFAS MP/NP removal, but their simultaneous removal has rarely explored. Herein, we report a library polymer-based, cationic nanoparticle networks (CNN) with systematic variation in surface charge density, polymer molecular weight, size anionic from aqueous solutions. These are synthesized three, one-pot steps starting polymerization-induced self-assembly (PISA) followed by rapid photocuring quaternary ammonium salt formation resulting 3D consisting solely nanoparticles. Our best performing CNN material demonstrated record-high MP capacities Qmax = 1865 mg/g KF 58.0 (mg/g)(L/mg)1/n based on Langmuir Freundlich isotherm model estimations, respectively. Furthermore, efficient NPs MPs complex water media, such as seawater at different pH values, demonstrating overall applicability.
