Thanks to the superior photoluminescence performance of lanthanide(III) ions sensitized by organic ligands via an "antenna effect" and host–guest interactions between a MOF material targeted analytes, nanoporous can achieve luminescence dynamics through influence thus endowing with ratiometric sensing application. Consequently, 3D Eu(III) based material, {[Eu(BPDC)(μ3–OH)(H2O)]·H2O·DMF}n (Eu-MOF, 2,2′-bipyridine-4,4′-dicarboxylic acid = H2BPDC), assembled H2BPDC ligand Eu3+ for achieving on–off inflammatory marker neopterin (Neo) detection, has been fabricated. The Eu-MOF is consist 1D Eu(μ3–OH) chains, which could further be connected deprotonated build framework, showing nanosized aperture ca. 12.6 Å × along a-direction. titration experiments demonstrate that exhibit simultaneous behavior Neo, regulating interactions. More importantly, visible color change observation from red bluish violet naked eyes in response concentrations Neo indicator facile achieved luminescent test strips portable hydrogels. A combination competitive absorption contribute confirmed UV–vis spectral overlap experiment density functional theory calculations.

Baicalin nanodelivery system based on functionalized metal-organic framework for targeted therapy of osteoarthritis by modulating macrophage polarization

Journal of Nanobiotechnology, Год журнала: 2024, Номер 22(1)

Опубликована: Май 9, 2024

Abstract Intra-articular drugs used to treat osteoarthritis (OA) often suffer from poor pharmacokinetics and stability. Nano-platforms as drug delivery systems for are promising OA therapy. In this study, we reported an M1 macrophage-targeted system Bai@FA-UIO-66-NH 2 based on folic acid (FA) -modified metal-organic framework (MOF) loaded with baicalin (Bai) antioxidant agent With outstanding biocompatibility high loading efficiency, could be specifically uptaken by LPS-induced macrophages serve a potent ROS scavenger, gradually releasing Bai at the subcellular level reduce production, modulate macrophage polarization M2, leading alleviation of synovial inflammation in joints. The synergistic effect scavenging significantly improved therapeutic efficacy OA, which may provide new insight into design precision
