“…It is a three-dimensional framework structure composed of terephthalic acid and metal cluster Zn 4 O ( Figure 2) [26], firstly synthesized by Yaghi et al [27]. MOF-5 has open skeleton structure, controlled pore structure and pore surface area and high thermal stability function [28][29][30], which has been widely studied in gas storage [31] and separation [32], electrochemistry [33], catalysis, and medicine [34]. In particular, the study of MOF-5 as drug carriers has received much attention in recent years.…”

Oridonin (ORI) is a natural active ingredient with strong anticancer activity. But its clinical use is restricted due to its poor water solubility, short half-life, and low bioavailability. The aim of this study is to utilize the metal organic framework material MOF-5 to load ORI in order to improve its release characteristics and bioavailability. Herein, MOF-5 was synthesized by the solvothermal method and direct addition method, and characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Thermogravimetric Analysis (TG), Brunauer–Emmett–Teller (BET), and Dynamic Light Scattering (DLS), respectively. MOF-5 prepared by the optimal synthesis method was selected for drug-loading and in vitro release experiments. HepG2 cells were model cells. MTT assay, 4′,6-diamidino-2-phenylindole (DAPI) staining and Annexin V/PI assay were used to detect the biological safety of blank carriers and the anticancer activity of drug-loaded materials. The results showed that nano-MOF-5 prepared by the direct addition method had complete structure, uniform size and good biocompatibility, and was suitable as an ORI carrier. The drug loading of ORI@MOF-5 was 52.86% ± 0.59%. The sustained release effect was reliable, and the cumulative release rate was about 87% in 60 h. ORI@MOF-5 had significant cytotoxicity (IC50:22.99 μg/mL) and apoptosis effect on HepG2 cells. ORI@MOF-5 is hopeful to become a new anticancer sustained release preparation. MOF-5 has significant potential as a drug carrier material.

“…28,29 Also, the dispersive forces for some MOFs are weak due to the high amount of void spaces. 30 To overcome these disadvantages, composites have been prepared by combining MOFs with other substrates 31,32 as graphene, 33 carbon nanotubes, 34 activated carbon, 35 metals 36 and silica. 37 Composites are considered as multicomponent materials which have special properties and many applications in the removal of pollutants and in the catalysis eld.…”

“…is work is aimed at exploring the application of polycarbonate microchips with the CuBTC-monopol monolithic disk as dye extraction supports. HKUST-1 that constitutes one extensively examined MOF, experimentally and theoretically, is obtained from benzene-1,3,5-tricarboxylate (BTC) connecter molecules and Cu 2+ cations, which contain paddle wheel structures [62][63][64][65]. In the present study, HKUST-1 is utilized as a MOF model for demonstrating in situ stratum-by-stratum self-assembly technique for grafting MOFs on poly(BuMA-co-EDMA) (butyl methacrylate-co-ethylene dimethacrylate) monolith surfaces.…”

In the present study, preparation of CuBTC-monopol monoliths for use within the microchip solid phase extraction was undertaken through a 20-min UV lamp-assisted polymerization for 2,2-dimethoxy-2-phenyl acetophenone (DMPA), butyl methacrylate (BMA), and ethylene dimethacrylate (EDMA) alongside inclusion of the porogenic solvent system (1-propanol and methanol (1 : 1)). The resultant coating underwent coating using CuBTC nanocrystals in ethanolic solution of ethanolic solution of 1,3,5-benzenetricarboxylic acid (H3BTC, 10 mM) and 10 mM copper(II) acetate Cu(CH3COO)2. This paper reports enhanced extraction, characterization, and synthesis studies for porous CuBTC metal organic frameworks that are marked by different methods including SEM/EDAX analysis, atomic force microscopy (AFM), and Fourier-transform infrared spectroscopy (FT-IR). The evaluation of the microchip’s performance was undertaken as sorbent through retrieval of six toxic dyes (anionic and cationic dyes). Various parameters (desorption and extraction step flow rates, volume of desorption solvent, volume of sample, and type of desorption solvent) were examined to optimize dye extraction using fabricated microchips. The result indicated that CuBTC-monopol monoliths were permeable with the ability of removing impurities and attained high toxic dye extraction recovery (83.4–99.9%). The assessment of reproducibility for chip-to-chip was undertaken by computing the relative standard deviations (RSDs) of the six dyes in extraction. The interbatch and intrabatch RSDs ranged between 3.8 and 6.9% and 2.3 and 4.8%. Such features showed that fabricated CuBTC-monopol monolithic disk polycarbonate microchips have the potential of extracting toxic dyes that could be utilized for treating wastewater.
