To study the effect of low power microwaves (950 MHz) on some structural and functional properties of liposomes which represent a good cell membrane model. The main objective was to eliminate the heat effect, as claimed by many authors to be the only effect of microwaves.

The amount of detergent needed to completely solubilize the liposomal membrane was increased after microwave exposure of liposomes, indicating an increased membrane resistance to the detergent and hence a change in the natural membrane permeation properties.
The data of the FTIR spectroscopy showed spectral changes in the exposed liposome preparations probably due to water loss and molecular conformational changes.
The flow activation energy measurements showed, that low power microwave exposure induced changes in the liposomes deformability (liposome fluidity was decreased and liposome rigidity was increased).
The authors conclude that low power microwaves of 950 MHz induced structural and functional changes in liposomes.
