Magnetic MOF for AO7 Removal and Targeted Delivery

Abstract

Owing to their high surface area and porosity, metal-organic frameworks (MOFs) have been gradually employed for a myriad of applications ranging from sensing, pollutant adsorption, and drug delivery to environmental remediation and catalysis. Magnetic nanoparticles-metal-organic frameworks (MMOFs) hybrid materials can facilitate facile removal of MOFs from solutions. In this report, we report the synthesis of Fe 3 O 4 @UiO-66 by encapsulation and simulated the drug loading and release by studying the adsorption and release of AO7. Thus, we loaded these MMOFs with AO7 and found that they were able to trigger and control its release by simply applying an external magnetic field. The magnetic field heats the magnets in the MOF, which causes the load to burst from the framework.

Carbonized Lanthanum-Based Metal-Organic Framework with Parallel Arranged Channels for Azo-Dye Adsorption

“…There the adsorption experiments were conducted at aqueous solution anionic MO dye with different times at a temperature of 298 K. Dye removal of examined MgAl-LDH/Cu-(BDC) metal−organic framework shows efficiency over 99 % after 20 min and reaches adsorption capacity over 600 mg g −1 [ 23 ]. Xue-Qing Zhan et al proposed the application of the UiO-66 MOF structure with incorporated iron oxide as an effective magnetic dye adsorbent [ 24 ]. Zinc based MOFs showed one of the highest surface areas and are one of the most studied MOF group [ 25 ].…”

“…The broad intensity at after 3390 cm -1 indicates to (OH) stretching vibrations of the coordinated water-molecules [16] . The peaks at 1580 and 1660 cm -1 characteristic asymmetric of COOgroup, whiles the peaks at 1385 and 1477 cm -1 characteristic symmetric of COOgroup [17][18][19] . The appeared peak at 1100 -1110 cm -1 is related to the C-O stretching vibration [22,27] .…”

Assessment of Crystalline Materials for Solid State Lighting Applications: Beyond the Rare Earth Elements

“…Metal-organic frameworks (MOFs), or coordination polymers, are a class of regular crystalline solids with well-organized host structures formed by metal cations coordinated with organic units [94]. Although MOFs are widely studied for different applications ranging from catalysis [95,96], non-linear optics [97], and magnetism [98], they present a high potential for luminescent devices given the possibility of incorporating a light-emitting cluster directly in the organic/metal mesh, allowing the modulation of luminescent properties [99,100]. The luminescence can be obtained as a metal-centered emission or luminescent absorbates, related to the organic liker through a ligand localized emission or metal-to-ligand charge transfer.…”
