A Mitra et al.
Indian journal of biochemistry & biophysics, 29(5), 411-414 (1992-10-01)
The acidic capsular polysaccharide isolated from Klebsiella K7 induced metachromasy in the cationic dye pinacyanol chloride indicating its chromotropic character. Interaction of the biopolymer with the cationic dye was studied by visible absorption spectrophotometry, and thermodynamic parameters of the interaction

Liposome is one of the major areas of interest in recent years because of its many potential applications. In this paper, three phase states of liposome (micelle, lamellar and reversed hexagonal) were prepared by thin-film hydration method and their structures
Raimon Sabaté et al.
Biopolymers, 72(6), 455-463 (2003-10-31)
The binding of pinacyanol (PIN), a cationic cyanine dye, to beta-amyloid fibrils (Abeta), which are associated with Alzheimer disease, was quantified by absorption spectrophotometry to measure the concentration of PIN bound to Abeta as a function of the Abeta concentration
S Dasgupta et al.
Indian journal of biochemistry & biophysics, 46(2), 192-197 (2009-06-13)
Capsular polysaccharides (SPS) are an integral component of gram-negative bacteria, and also have potential use as vaccine. In this paper, interactions of SPS isolated from Klebsiella strains K20 and K51 with cationic dyes pinacyanol chloride (PCYN) and acridine orange (AO)
