| Zirconium phosphates (ZrP) are acidic, inorganic cation exchange materials with layered structures. We are interested in the photophysics, photochemistry and electrochemistry of organic and inorganic molecules intercalated into a hydrated phase of ZrP (10.3 Å-ZrP). Particularly, we are interested in the study of how these properties are affected in the nanoenvironment of the intergalleries and how the intercalated materials might be used in biosensors and drug carriers. I will present the characterization of insulin intercalated-zirconium phosphate. The synthesis of the 10.3 Å-ZrP phase and the intercalation of insulin were successful and the intercalated materials were characterized. The intercalation of insulin into the zirconium phosphate layers produced a new phase with a ca. 49 Å interlayer distance, as determined by X-ray powder diffraction (XRPD) data and the FTIR spectrum showed the characteristic bands of insulin in the intercalated material. The XPS data showed that insulin is present in the ZrP galleries and the UV-vis absorption spectrum shows marked differences between insulin in solution and insulin intercalated in ZrP. The complete characterization of these materials using analytical techniques such as XRPD, XPS, UV-vis spectrophotometry, and FTIR spectroscopy, among others, will be presented. These materials will be used to develop insulin carriers. |
