Multifunctional ZnO:Gd@ZIF-8 hybrid nanocomposites with tunable luminescent-magnetic performance for potential bioapplication
Abstract
Novel multifunctional ZnO:Gd@ZIF-8 hybrid inorganic-organic nanocomposites with tunable luminescent-magnetic performance were successfully fabricated using wet chemistry synthesis routes. Physico-chemicalcharacterization including crystal structure, phase compositions, morphology, surface properties, as well asphotoluminescent and magnetic characteristics was performed using powder X-ray diffraction (XRD), FT-IRanalysis, transmission and scanning electron microscopies (TEM/SEM), N2 adsorption/desorption, SQUIDmagnetometer, and photoluminescence spectroscopy. The biological studies of obtained materials, such ascytotoxicity profile and in vitro MRI imaging also investigated for potential use as contrast agents. Resultsshowed that the doping with Gd3+ in a broad concentration range and the presence of ZIF-8 layer on ZnO affectthe physico-chemical properties of the obtained composites. The obtained porous ZnO:Gd@ZIF-8 compositeswere highly crystalline with a large surface area. The XRD study indicated the formation of hexagonal wurtzitestructure for ZnO and ZnO:Gd3+ (1–5 at.%). Luminescent studies showed, that ZnO is an ideal matrix for theincorporation of Gd3+ ions in a broad concentration range with efficient green luminescence. The PL intensityreached the maximum up to 5 at.% of Gd3+. The zeta potential values indicated the good stability of obtainednanoparticles. Proposed new materials with paramagnetic behavior and outstanding MR imaging capabilitycould be used as potential contrast agents for magnetic resonance imaging.
