Organic Framework

Metal organic frameworks (MOFs) are one of those compounds which have drawn attention in various applications due to their several interesting properties like tunable shape, size, pore size, easy functionalization, high surface area, pore volume, etc. Metal organic frameworks due to their uniform structures, tunable porosity, wide variety and stability on various topology, geometry, dimension and chemical functions of the molecular network give a remarkable structural diversity in comparison to other porous materials. This enables scientists to handle numerous framework structures, porosity and functionality effectively. The unique structural architecture and tunable properties of MOF’s makes them an interesting hybrid material consisting of organic and inorganic materials. MOF can be randomly constructed like Lego bricks and superior in terms of versatility in comparisson to other porous materials. A number of MOFs containing a wide variety of metal e.g. zinc, copper, iron, aluminium, magnesium, chromium, zirconium, gadolinium, manganese are gaining rapid growth in commercial markets for gas storage, adsorption, separation and catalytic applications. This concise review emphasizes various synthetic methods e.g. solvothermal process, hydrothermal synthesis, electrochemical synthesis, microwave synthesis, sonochemical synthesis, mechanochemical synthesis, of metal organic framework developed in the last few decades. It also addresses various applications of metal organic framework e.g. hydrogen storage, gas adsorption, drug delivery systems and bioimaging agents, biocatalysts, biosensors, electrochemical sensors, etc. It also comments on various challenges and futuristic applications of metal organic frameworks in various field e.g. liquid wate management, gaseous waste management, sunlight assisted catalysis, water purification, building materials, electronic devices, battery technologies, targeted drug delivery, solar cells, etc. of science and technology in coming decades.

Background: To date, a number of new and attractive materials have been applied in drug delivery systems (DDDs) to improve the efficiency of the treatment of cancers. Some problems like low stability, toxicity, and weak ability of targeting have hampered most of the materials for further applications in biomedicine. MIL(MIL = Materials of Institute Lavoisier), as a typical subclass of metal-organic frameworks (MOFs), owns more advantages than other subclass MOFs, such as better biodegradability and lower cytotoxicity. However, until now, systematic conclusions and analyses of Fe-based MIL on medical applications are rare, even though the majority of documents have discussed one research branch of the porous materials MOFs. Discussion: In this review, we're going to focus mainly on the latest studies of applications, including bioimaging, biosensing, and antibacterial and drug delivery on Fe-based MIL. The existing shortcomings and future perspectives of the rapidly growing biomedical applications of Fe-based MIL materials addressing dosage and loading strategies issues are also discussed briefly.. Further studies with the use of different therapies will be of great interest. Conclusion: This article reviews the Fe-based MOFs design and biomedical application, including biosensing, bioimaging, antibacterial agent, and drug delivery in recent years.

In recent years, Metal-Organic Frameworks (MOFs) have attracted a growing interest for biomedical applications. The design of MOFs should take into consideration the subtle balance between stability and biodegradability. However, only few studies have focused on the MOFs’ stability in physiological media and their degradation mechanism. Here, we investigate the degradation of mesoporous iron (III) carboxylate MOFs, which are among the most employed MOFs for drug delivery, by a set of complementary methods. In situ AFM allowed monitoring with nanoscale resolution the morphological, dimensional, and mechanical properties of a series of MOFs in phosphate buffer saline and in real time. Depending on the synthetic route, the external surface presented either well-defined crystalline planes or initial defects, which influenced the degradation mechanism of the particles. Moreover, MOF stability was investigated under different pH conditions, from acidic to neutral. Interestingly, despite pronounced erosion, especially at neutral pH, the dimensions of the crystals were unchanged. It was revealed that the external surfaces of MOF crystals rapidly respond to in situ changes of the composition of the media they are in contact with. These observations are of a crucial importance for the design of nanosized MOFs for drug delivery applications.
