"Changes of the direction of vesicle movement are demonstrated, which occur only during irradiation with a "switch on" of the effect. This MMW-induced effect was observed at a larger extent on giant vesicles prepared with negatively charged phospholipids. The monitoring of induced-by-irradiation temperature variation and numerical dosimetry indicate that the observed effects in vesicle movement cannot be attributed to local heating."
"The enhancement of the CA reaction rate was observed at a lesser extent on liposomes with a larger diameter and, in turn with leaflets less bent. The different packing of the phospholipid bilayer-due to the higher curvature-could be a critical factor in eliciting membrane permeability changes indicating a possible role for water molecules bound to functional groups in the glycerol region. Since numerical dosimetry indicates that the temperature rise during the exposure was negligible, the observed effects cannot be attributed to heating of the samples."
