In the Caran lab, we use the tools of organic synthesis to make novel compounds in an effort to develop self-assembled soft materials (colloids) with well-defined properties. We subsequently use a wide variety of tools and analytical methods to measure the properties and to understand the modes of self-assembly of the colloidal aggregates formed by these novel compounds.
For example, we have developed a series of organogelators (compounds that form gels in organic solvents) which self assemble via a combination of hydrogen bonding and pi-pi stacking of complementary arenes [in collaboration with Dr. Michal Sabat and Dr. Lin Pu at the University of Virginia].
In another project, we have prepared a number of surfactants with two polar head groups and one non-polar tail which self assemble into micelles in an aqueous environment. These compounds show unique properties when compared to conventional surfactants with one head and one tail. We are currently examining both colloidal and antimicrobial properties of these novel compounds, in collaboration with Dr. Kevin P. C. Minbiole (JMU Chemistry & Biochemistry) and Dr. Kyle Seifert (JMU Biology).
Students in the Caran lab synthesize, purify and analyze the structure of these novel molecules, and subsequently study the self-assembled materials using an arsenal of analytical techniques including nuclear magnetic resonance (NMR) spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), optical microscopy, differential scanning calorimetry (DSC), surface tensiometry, conductivity and attenuated total reflectance infrared (ATR-IR) spectroscopy.
