Abstract
Metal-organic frameworks (MOFs) have a good designability, a well-defined pore, stimulus responsiveness, a high surface area, and a controllable morphology. Up to now, various MOFs have been widely used as nanocarriers and have attracted lots of attention in the field of drug delivery and release because of their good biocompatibility and high-drug-loading capacity. Herein, we provide a comprehensive summary of MOF-based nanocarriers for drug delivery and release over the last five years. Meanwhile, some representative examples are highlighted in detail according to four categories, including the University of Oslo MOFs, Fe-MOFs, cyclodextrin MOFs, and other MOFs. Moreover, the opportunities and challenges of MOF-based smart delivery vehicles are discussed. We hope that this review will be helpful for researchers to understand the recent developments and challenges of MOF-based drug-delivery systems.

Abstract
![]()
Adsorption and controlled release of agrochemicals has
been studied
widely using different nanomaterials and a variety of formulations.
However, the potential for application of high surface-area metal–organic
frameworks (MOFs) for the controlled release of agrochemicals has
not been thoroughly explored. Herein, we report controlled and sustainable
release of a widely used herbicide (2-methyl-4-chlorophenoxyacetic
acid, MCPA) via incorporation in a range of zirconium-based MOFs and
their biodegradable polymer composites. Three Zr-based MOFs, viz.,
UiO-66, UiO-66-NH2, and UiO-67 were loaded with MCPA either
postsynthetically or in situ during synthesis of the MOFs. The MCPA-loaded
MOFs were then incorporated into a biodegradable polycaprolactone
(PCL) composite membrane. All three MOFs and their PCL composites
were thoroughly characterized using FT-IR, TGA, SEM, PXRD, BET, and
mass spectrometry. Release of MCPA from each of these MOFs and their
PCL composites was then studied in both distilled water and in ethanol
for up to 72 h using HPLC. The best performance for MCPA release was
observed for the postsynthetically loaded MOFs, with PS-MCPA@UiO-66-NH2 showing the highest MCPA concentrations in ethanol and water
of 0.056 and 0.037 mg/mL, respectively. Enhanced release of MCPA was
observed in distilled water when the MOFs were incorporated in PCL.
The concentrations of herbicides in the release studies provide us
with a range of inhibitory concentrations that can be utilized depending
on the crop, making this class of composite materials a promising
new route for future agricultural applications.

Abstract
Metal-organic frameworks (MOFs), particularly Zirconium based, have a wide variety of potential applications, such as catalysis and separation. However, these are held back by traditionally only being synthesised in long batch reactions, which causes the process to be expensive and limit the amount of reaction control available, leading to potential batch to batch variation in the products, such as particle size distributions. Microfluidics allows for batch reactions to be performed with enhanced mass/heat transfer, with the coiled flow inverter reactor (CFIR) setup narrowing the residence time distribution, which is key in controlling the particle size and crystallinity. In this work, a Zirconium based MOF, UiO-67, has been synthesised continuously using a microfluidic CFIR, which has allowed for the product to be formed in 30 min, a fraction of the traditional batch heating time of 24 h. The microfluidicially synthesised UiO-67 is also smaller product with a narrower particle size distribution (≈200 nm to ≈400 nm) than its batch counterpart (~500 nm to over 3 µm).

Abstract
Cancers of the gastrointestinal tract constitute one of the most common cancer types worldwide and a ∼58% increase in the global number of cases has been estimated by IARC for the next twenty years. Recent advances in drug delivery technologies have attracted scientific interest for developing and utilizing efficient therapeutic systems. The present review focuses on the use of nanoscale MOFs (Nano-MOFs) as carriers for drug delivery and imaging purposes. In pursuit of significant improvements to current gastrointestinal cancer chemotherapy regimens, systems that allow multiple concomitant therapeutic options (polytherapy) and controlled release are highly desirable. In this sense, MOF-based nanotherapeutics represent a significant step towards achieving this goal. Here, the current state-of-the-art of interdisciplinary research and novel developments into MOF-based gastrointestinal cancer therapy are highlighted and reviewed.

Aluminum-based metal-organic frameworks for adsorptive removal of anti-cancer (methotrexate) drug from aqueous solutions. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2021; 277:111448. [PMID: 33254841 DOI: 10.1016/j.jenvman.2020.111448] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 09/20/2020] [Accepted: 09/26/2020] [Indexed: 05/16/2023]
Abstract
A series of metal-organic frameworks (MOFs) based on aluminum-benzene dicarboxylates (MIL-53, NH2-MIL-53, and NH2-MIL-101) at different ratios have been synthesized, and their adsorption performances for methotrexate (MTX), an anti-cancer drug, have been investigated in terms of adsorption kinetics, isotherms, solution pH, thermodynamics, mechanism, and recyclability. Maximum adsorption values of 374.97, 387.82, and 457.69 mg/g were observed for MIL-53, NH2-MIL-53, and NH2-MIL-101 , respectively. Our study shows that adsorption capacity of MTX depends not only on surface area and pore volume but also on the zeta potential and the presence of suitable functional groups. Higher adsorption of NH2-MIL-101 observed for MTX than the other synthesized MOFs may be attributed to its large surface area, large total pore volume, high positive zeta potential, and polar amino functional groups located on its surface, which are responsible for its increased interactions with MTX molecules. Adsorption isotherms and kinetics of MTX onto NH2-MIL-101 followed the Langmuir and pseudo-second-order kinetic equations. Thermodynamic data suggest that adsorption of MTX onto NH2-MIL-101 is spontaneous and exothermic, while the adsorption mechanism is governed by electrostatic interactions, π-π stacking interactions, and H-bonding. Regeneration and recyclability of NH2-MIL-101 were also investigated by washing with ethanol to observe its decreased adsorption performance towards MTX. It was slightly decreased after seven adsorption-desorption cycles, indicating excellent regeneration and good structural stability under the chosen experimental conditions.
