Biological applications of functionalized calixarenes.

The functionalized calixarene derivatives exhibit remarkable properties towards organic and bioorganic molecules. However, the ability of calixarene derivatives to form stable complexes with biomolecules allows them to be applied for the development of biosensors and in the field of biology, biotechnology, and drug discovery. The applications of the functionalized calixarenes are summarized in this review, and an outlook for the future developments is discussed. A brief survey (of the last 10 years) on their biological application in various fields is also considered (199 references).
