Recent progress of metal–organic frameworks as sensors in (bio)analytical fields: towards real-world applications

Analytical and Bioanalytical Chemistry, Год журнала: 2023, Номер 415(11), С. 2005 - 2023

Опубликована: Янв. 4, 2023

Abstract The deployment of metal–organic frameworks (MOFs) in a plethora analytical and bioanalytical applications is growing research area. Their unique properties such as high but tunable porosity, well-defined channels or pores, ease post-synthetic modification to incorporate additional functional units make them ideal candidates for sensing applications. This possible because the interaction analytes with MOF often results change its structure, eventually leading intrinsic physicochemical which then transduced into measurable signal. porosity allows adsorption very efficiently, while pore sizes/nature and/or installation specific recognition groups allow modulating affinity towards different classes compounds, turn lead good sensor sensitivity selectivity, respectively. Some figures are given illustrate potential MOF-based sensors most relevant application fields, future challenges opportunities their translation from academia (i.e., laboratory testing properties) industry real-world devices) critically discussed.
