In this work, the development of novel magnetic nanocomposite microparticles (MNMs) via free radical polymerization for their application in the remediation of contaminated water is presented. Acrylated plant-based polyphenols, curcumin multiacrylate (CMA) and quercetin multiacrylate (QMA), were incorporated as functional monomers to create high affinity binding sites for the capture of polychlorinated biphenyls (PCBs), as a model pollutant. The MNMs were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, dynamic light scattering, and UV-visible spectroscopy. The affinity of these novel materials for PCB 126 was evaluated and fitted to the nonlinear Langmuir model to determine binding affinities ( ). The results suggest the presence of the polyphenolic moieties enhances the binding affinity for PCB 126, with values comparable to that of antibodies. This demonstrates that these nanocomposite materials have promising potential as environmental remediation adsorbents for harmful contaminants.

A free radical polymerization approach was applied to synthesize different carboxymethyl cellulose-grafted poly(acrylamide) hydrogels (Hyd) composited with biochar, magnetic biochar, and magnetic biochar decorated with ZIF-67 to decontaminate methylene blue (MB) from water media. Biochar was obtained from walnut shells (WS) by a pyrolysis method, and magnetic biochar (WS/CoFeO) and biochar-decorated ZIF-67 (WS/CoFeO/ZIF-67) were prepared by chemical co-precipitation and hydrothermal methods, respectively. An increase in the amount of these particles by up to 10 wt% enhanced the removal performance.

Increase in breast cancer has led to the search for systems that can enable, targeted, sustained and prolonged release of drugs while simultaneously reducing the side effects posed by them. In light of this, folic acid-conjugated 5-Fluorouracil and doxorubicin loaded chitosan/Fe₃O₄ (FA-dual@CS/Fe₃O₄) nanocomposite has been synthesized using the chemical method for targeted breast cancer therapy in addition to CS/FeO and dual drug encapsulated CS/FeO. FTIR and XPS studies confirm the successful drug encapsulation and FA conjugation.

Point-of-care (POC) detection of prostate-specific antigen (PSA) is critical for the early screening and monitoring of prostate cancer (PCa), which facilitates timely intervention and personalized treatment. However, existing POC platforms suffer from inadequate detection sensitivities, susceptibility to matrix interference, and complex sample pretreatment. To address these issues, we proposed a naked-eye and colorimetric sensing platform based on magnetic nanozyme (FeO@ZIF-67@Pt) integrated with a tetrahedral DNA framework (TDF) and alkaline phosphatase (ALP)-triggered hydrolysis reaction for PSA detection with superior sensing performances.

Background: Organophosphate tri-esters (tri-OPEs), widely used flame retardants, include alkyl-, halogenated-, and aryl-substituted types with distinct physicochemical properties. They may readily enter the ambient environment through volatilization, mechanical abrasion, and dissolution mechanisms occurring throughout the product lifecycle. To date, a range of monitoring methodologies incorporating sample pretreatment techniques have been developed to characterize the environmental distribution of tri-OPEs.
