Micellar effect of CTAB on Phenol red sodium salt: A model system may be used for cell membrane study

Abstract

This communication reports the effect of micelles on the molecular organisation of an anionic fluorescent dye Phenol Red Sodium salt (PRSS) in Langmuir-Blodgett (LB) film. PRSS is a water soluble anionic fluorescent dye generally used as a pH marker for cell tissue culture. Below and Above CMC of CTAB the spectral characteristics.Of PRSS molecules changes which confirms the interactions of the PRSS molecules with micelles of the CTAB. UV–vis absorption and fluorescence spectroscopic studies confirm this. So we can modified the spectral behavior of the PRSS molecules in solution as well as in LB films which may be useful as an indicator in different biological process.
