About the Seminar:

Our research has explored unique applications of room-temperature ionic liquids (RTILs) for several years. More recently, we have extended the range of these materials to include applications of similar solid phase materials, i.e. organic salts with melting points of frozen ionic liquids (25 °C to 100 °C) up to melting points of 250 °C. To contrast and better define these new materials from RTILs, we have created an acronym, GUMBOS (Group of Uniform Materials Based on Organic Salts). Our GUMBOS have the tunable properties frequently associated with RTILs, including tunable solubility, melting point, viscosity, thermal stability, and functionality. Thus, these properties allow production of solid phase materials with a wide range of properties, and also a wide range of applications. Select applications of GUMBOS and nanoscale GUMBOS that we have recently explored will be highlighted. We have also designed nanomaterials based on this strategy and have designated these materials as nanoGUMBOS. We believe that our methodology for preparing GUMBOS and nanoGUMBOS represent an extremely useful approach to production of tunable materials and tunable nanomaterials since our materials can be designed and assembled for specific uses, rather than simply adapted for use as for most materials. In this talk, I will also highlight selected applications, including sensor applications and cancer therapy. Specific emphasis will be placed on the unique advantages attained from use of GUMBOS and nanoGUMBOS. In particular, we have found these materials to be uniquely suited for applications ranging from cancer therapy, selective extraction, molecular weight determination, and solar cells. Particular emphasis will be placed on applications in the general areas of analytical chemistry and the biomedical sciences.
