Cationic amino acid-based surfactants are known to interact with the lipid bilayer of microorganism resulting in cell death through a disruption of the membrane topology. To elucidate the interaction of a cationic surfactant synthesized in our lab, i

The strong UV absorption of the bromide in aqueous solution undergoes a remarkable red shift of more than 10 nm induced by the addition of the salts that constitute a saline buffer. The maximum absorption wavelength of the bromide is displaced from a

A novel arginine-based cationic surfactant Nα-benzoyl-arginine dodecylamide (Bz-Arg-NHC12) was synthesized in our laboratory. In this paper we study the interaction of Bz-Arg-NHC12 with sheep and human red blood cells (SRBC and HRBC respectively) du
