An overview of Metal–Organic Frameworks as potential platform for sensing application to environmental pollutants and drug delivery

Metal Organic Frameworks (MOFs) represent a novel class of materials, characterized by their ability to form extended porous crystalline structures through the linkage of inorganic clusters or metallic ions with organic ligands. The availability of broad range of metal centres and type of organic linkers gives us opportunity for tailoring physical and chemical properties of MOFs. These modified MOFs opens up new channels for the customization of new devices needed for specific purposes. Though MOFs have been explored for various applications in different sectors such as gas storage, proton conduction, biotechnological, biomedical sector, catalysis, and separation, but drug delivery and the sensing applications has been taken exclusively in the present review. So, this review paper entails an overview of various synthetic methods of low dimensional MOFs such as 1D and 2D MOFs, and also focuses on their applications in sensing and drug delivery. This stems from their remarkable catalytic chemistry and their compatibility with a broad spectrum of materials. Moreover, the 2D layered structure of MOFs and their distinctive coordination of metal ions with organic ligands have sparked interest in recent years.
