In the present work, we study the shear-induced transformation of polymer-rich lamellar phases into vesicles. The evolution of vesicle size is studied by different scattering techniques, rheology, and microscopy methods. The lamellar phase found in the system D2O/ o-xylene/ Pluronic

The effects of octyltrimethylammonium ions (OTMA+), octyl sulphate ions (OS-) and octanoic acid (OA) on the sodium current of the voltage-clamped squid giant axon have been investigated using intracellular and extracellular application of the test substances. OTMA+ applied externally at

The local anaesthetic effect of cationic, anionic, and neutral alkyl amphipathic agents was similarly enhanced in an apparently nonspecific way by circumstances which modulate electrostatic interactions (acidity, modification of charged groups at the sarcolemmal surface by group-specific reagents, or changes

We present a molecular dynamics simulation at 300 K in explicit solvent environment of chloroform of the stoichiometric complex formed by poly(alpha,L-glutamate) and octyltrimethylammonium ions. We observed that the alpha-helix conformation of the polypeptide chain remains stable during a 2-ns

The interaction of cationic surfactants with single dsDNA molecules has been studied using force-measuring optical tweezers. For hydrophobic chains of length 12 and greater, pulling experiments show characteristic features (e.g. hysteresis between the pulling and relaxation curves, force-plateau along the
