Experimental investigations of micellar systems

In this article we report an investigation of micellar systems by photon correlation technique for the first time. The systems investigated are two very commonly occurring Directo dyes (Congored and Benzopurpurine 4B) in aqueous solutions. From these studies, we are able to exploit their aggregation trends at different dye and salt concentrations and to also compare with available data from other conventional techniques used so far. The conventional methods (microdiffusion cells, ultracentrifuge methods, etc.) often produce controversial results unlike the present technique which is consistent, accurate, and very fast.
