Metal-organic frameworks-based band-aids for bioanalysis

Irina Guerra-Martín, Nicole Fledderus, Ángela Sánchez-Hernández, Atteneri López‐Arencibia et autres

Sweat offers a compelling, non-invasive matrix for continuous bioanalytical monitoring, yet its exploitation remains limited by difficulties associated to its low sample volumes, compositional variability, low content of target compounds, and inadequate tools for proper monitoring. While certainly metal-organic frameworks (MOFs) constitute …

Facile preparation of UiO-66(Zr)-based mixed matrix membranes for thin-film solid-phase microextraction: Application to alkyl- and chlorophenols from environmental waters

Santiago D. Cabrera-González, Massimo Giuseppe De Cesaris, María J. Trujillo-Rodríguez, Adrián Gutiérrez-Serpa et autres

This study reports a simple strategy for integrating metal-organic frameworks (MOFs) composites in thin film solid-phase microextraction devices. In particular, the UiO-66( Zr ) MOF was successfully combined with polystyrene, forming a composite that was coated onto paper supports via dip coating. …

Mixed matrix membranes based on cellulose acetate recycled from cigarette butts and metal-organic frameworks for thin film solid-phase microextraction: Determination of phenols in environmental waters

Massimo Giuseppe De Cesaris, María J. Trujillo‐Rodríguez, Jorge Pasán, Alessandra Gentili et autres

The recovery of raw materials from waste is a viable strategy to transition to more circular and greener methodologies. In this study, cigarette filters were recycled to obtain cellulose acetate and re-used as a support for a sorbent material in a microextraction …

Saliva analysis using metal–organic framework-coated miniaturized vials

Iván Taima‐Mancera, María J. Trujillo‐Rodríguez, Jorge Pasán, Verónica Pino

In-vial microextraction is probably the simplest microextraction technique because it eliminates centrifugation and/or filtration steps while offering short extraction and desorption times. However, it has had limited applicability, mostly involving polydimethylsiloxane coatings and gas chromatography applications. Quite recently, one study introduced metal-organic …
