Polyoxometalates (POMs) are a class of metal-oxygen cluster anions with a wide range of structures and properties. They have been extensively studied for their potential applications in various fields, including catalysis, medicine, and materials science. In recent years, there has been growing interest in the use of POMs as drug transporters into the cell.

POMs have several features that make them attractive for this purpose. First, they are highly soluble in water, which is essential for their use in biological systems. Second, they are relatively non-toxic, which is important for any potential therapeutic application. Third, POMs can be easily functionalized with various ligands to improve their targeting and delivery properties.

One of the most promising applications of POMs as drug transporters is in the treatment of cancer. Cancer cells are often characterized by their rapid growth and high metabolic activity, which makes them particularly vulnerable to the effects of POMs. POMs can be used to deliver a variety of drugs to cancer cells, including chemotherapy drugs, radiation sensitizers, and gene therapy agents.

POMs have also been shown to be effective in the treatment of other diseases, such as infectious diseases, neurodegenerative disorders, and diabetes. In addition, POMs have been investigated for their use in the development of new drug delivery systems, such as liposomes and nanoparticles.

Overall, POMs show great promise as drug transporters into the cell. Their unique properties make them well-suited for this purpose, and they have demonstrated efficacy in the treatment of a variety of diseases. Further research is needed to fully explore the potential of POMs in this area.
