Determination of critical concentrations by synchronous fluorescence spectrometry

Analytical methods (impact factor: 1.55). 01/2012; 4(1):47-49. DOI:10.1039/C1AY05495C ISBN: 1759-9660 pp.47-49

ABSTRACT We demonstrate that by using constant wavelength synchronous fluorescence spectrometry (CW-SFS) critical concentrations of some types of aggregation can be quantified. Detection of aggregation associated with hydrogen bonding in Chlorin e6 and Triton X-100 suggest that CW-SFS may be a technique that can explore aggregation at much lower levels (dimer, trimer, oligomer, etc.)
