Fabrication of Biomimetic Cascade Nanoreactor Based on Covalent Organic Framework Capsule for Biosensing

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(29), P. 11052 - 11060

Published: July 12, 2023

The cooperation of biocatalysis and chemocatalysis in a catalytic cascade reaction has received extensive attention recent years, whereas its practical applications are still hampered due to the fragility enzymes, poor compatibility between carriers limited efficiency. Herein, biomimetic nanoreactor (GOx@COFs@Os) was presented by integrating glucose oxidase (GOx) Os nanozyme with covalent organic framework (COF) capsule using metal-organic (ZIF-90) as template. obtained GOx@COFs@Os provided capacious microenvironment retain conformational freedom GOx for maintaining activity, wherein enzyme activity COF capsules equal 92.9% free 1.88-folds higher than that encapsulated ZIF-90. Meanwhile, could protect against incompatible environments (high temperature, acid, solvents), resulting improved stability packaged enzymes. Moreover, great pore structure significantly affinity substrates facilitated efficient mass transfer, which achieved 2.19-folds improvement efficiency system, displaying performance reaction. More importantly, successfully employed monitoring, glutathione sensing, bisphenol S detection immunoassay proof-of-concept. Our strategy new avenue biocatalytic encourage wide various fields.

Identification of hazardous organic compounds in e-waste plastic using non-target and suspect screening approaches

Chemosphere, Journal Year: 2024, Volume and Issue: 356, P. 141946 - 141946

Published: April 9, 2024

End-of-life electric and electronic devices stand as one of the fastest growing wastes in world and, therefore, a rapidly escalating global concern. A relevant fraction these corresponds to polymeric materials containing plethora chemical additives. Some those additives fall within category hazardous organic compounds (HOCs). Despite significant advances capabilities analytical methods, comprehensive characterization WEEE plastic remains challenge. This research strives identify primary polymers by implementing non-target suspect screening approach. Gas chromatography coupled time-of-flight mass spectrometry (GC-QTOF-MS), using electron ionization (EI), was applied for detection identification more than 300 substances this matrix. preliminary comparison carried out with nominal resolution EI-MS spectra contained NIST17 library. BPA, flame retardants, UV-filters, PAHs, preservatives were among detected. Fifty-one confirmed authentic standards. The study establishes database m/z ratios accurate characteristic compounds, encompassing HOCs. Semi-quantification predominant conducted across 48 samples collected from handling dismantling facilities Galicia. ABS demonstrated highest median concentrations, ranging 0.154 4456 μg g

Material Cycles, Environmental Emissions, and Ecological Risks of Bisphenol A (BPA) in China and Implications for Sustainable Plastic Management

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 26, 2024

Bisphenol A (BPA) is a high-production-volume plastic chemical, with ∼98% of its usage in China allocated to producing polycarbonate and epoxy resin, fugitive release threatens ecosystems. However, knowledge anthropogenic cycles, environmental emissions, ecological risks remains incomplete, hindering effective lifecycle management. Herein, material flow analysis, multimedia modeling, risk assessment were integrated comprehensively map BPA dynamics China. Results reveal ∼ 90-fold increase consumption between 1992 2022 major applications shifted from optics packaging automotive, construction, electronics. held ∼34 Mt in-use stock (∼24 kg per capita), no indication reaching saturation. occurred throughout lifecycle, soil water primary sinks. Aquatic concentrations exceeded the limit national pollutant emission standards ∼8.4% Chinese mainland areas 2022, ∼4.5% suffered very high chronic aquatic organisms. Scenario analysis indicates that 90% reduction factors would be required avoid contamination all focus. Our findings contribute as scientific basis for sustainable management highlight need updated techniques, intensified monitoring, standardized regulations.
