Recent Trends

Materials science has seen a great deal of advancement and development. The discovery of new types of materials sparked the study of their properties followed by applications ranging from separation, catalysis, optoelectronics, sensing, drug delivery and biomedicine, and many other uses in different fields of science. Metal organic frameworks (MOFs) and covalent organic frameworks (COFs) are a relatively new type of materials with high surface areas and permanent porosity that show great promise for such applications. The current study aims at presenting the recent work achieved in COFs and MOFs for biomedical applications, and to examine some challenges and future directions which the field may take. The paper herein surveys their synthesis, and their use as Drug Delivery Systems (DDS), in non-drug delivery therapeutics and for biosensing and diagnostics.

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.

Background: Metal-organic frameworks (MOFs), as attractive hybrid crystalline porous materials, are increasingly being investigated in biomedical applications owing to their exceptional properties, including high porosity, ultrahigh surface areas, tailorable composition and structure, and tunability and surface functionality. Of interest in this review is the design and development of MOFbased drug delivery systems (DDSs) that have excellent biocompatibility, good stability under physiological conditions, high drug loading capacity, and controlled/targeted drug release. Objective: This review highlights the latest advances in MOFs as anticancer drug delivery systems (DDSs) along with insights on their design, fabrication, and performance under different stimuli that are either internal or external. The synthesis methods of MOFs, along with their advantages and disadvantages, are briefly discussed. The emergence of multifunctional MOF-based theranostic platforms is also discussed. Finally, the future challenges facing the developments of MOFs in the field of drug delivery are discussed. Methods: The review was prepared by carrying out a comprehensive literature survey using relevant work published in various scientific databases. Results: Novel MOFs in biomedical applications, especially in drug delivery, have shown great potentials. MOF-based DDSs can be classified into normal (non-controllable) DDSs, stimuli-responsive DDSs, and theranostic platforms. The normal DDSs are pristine MOFs loaded with MOFs and offer little to no control over the drug delivery. Stimuli-responsive DDSs offer better spatiotemporal control over the drug release by responding to either endogenous (pH, redox, ions, ATP) or exogenous stimuli (light, magnetism, US, pressure, temperature). The theranostic platforms combine stimuli-responsive drug delivery with diagnostic imaging functionality, paving the road for imaging-guided drug delivery. Conclusion: This review presented a summary of the various methods utilized in MOF synthesis along with the advantages and disadvantages of each method. Furthermore, the review highlighted and discussed the latest developments in the field of MOF-based DDSs and theranostic platforms. The review is focused on the characteristics of MOF-based DDSs, the encapsulation of different anticancer drugs as well as their stimuli-responsive release.

Abstract One of the challenges of the medicine is to improve the chemical stability of drugs and to prevent their premature biodegradation before reaching the therapeutic target. Various nanoparticles were used to solve this problem, but low drug loading efficiency limited their biomedical applications. Metal organic frameworks are promising candidates for drug delivery since they have extremely high surface area and regular porosity. In this study, we prepared high-crystalline MIL-53 frameworks based on aluminium and 2-aminoterephtalic acid by microwave-assisted synthesis and evaluated their properties as drug carriers. Drug loading of chemotherapeutic and diagnostic molecules of different nature riches value of 34% by particle weight, significantly higher than those of other reported solid nanoparticles. Therefore, our results make MIL-53 (Al) frameworks promising candidate for drug delivery.
