The interaction of two anthraquinone dyes, bromaminic acid 1-amino-4-bromo anthraquinone-2-sulphonic acid (BA) and 1-amino-4-(4'-aminophenylamino)-anthraquinone-2,3'-disulphonic acid (ASSO), with poly-L-lysine (PLL), poly-L-ornithine (PLO) and poly-L-arginine (PLA) has been studied. The flexibility of the side chain (chain length) and the geometry of the(More)
