Induced chirality of polycyclic aromatic hydrocarbons in aqueous bile salt solutions
- Duke Univ., Durham, NC (USA)
We will discuss the effects of organized bile salt phases on the chirality of several polycyclic aromatic hydrocarbons (PAHs), as investigated by transmission circular dichroism (CD) and fluorescence-detected circular dichroism (FDCD). Amphiphilic bile salt monomers form chiral micellar aggregates and should induce interesting changes in the chirality of the PAH probes. The high sensitivity of FDCD allows us to examine the effects of the organized bile salt media on the probe molecule over a large range of concentrations both above and below the critical micelle concentration (cmc) of the bile salt. The use of chiral bile salt media for FDCD determination of fluorescent analytes will be discussed.
