    This article belongs to the Special Issue Polyelectrolyte-Dye Interaction
    Abstract: The interaction of two anionic polyelectrolytes, namely, sodium alginate (NaAlg) & sodium heparin ate (NaHep) with a cationic dye Toluidine Blue (TB) has been investigated by spectrophotometric method. The polymers induced metachromasy in the dyes resulting in the shift of the absorption maxima of the dyes towards shorter wavelengths. The stability... Show More
