Effect of Pulsed Electric Fields on Interface Properties of Phospholipids Dispersion

Article Preview

Abstract:

Effects of pulsed electric fields (PEF) treatment on interface properties of phospholipids dispersion were studied. Results showed that the conductivity of solutions with different concentration after PEF treatment increased while surface tension value decreased with increasing electric field strength. The absolute value of zeta potential firstly increased when the field intensity was within 0~20 kV/cm, and then decreased if the field intensity increased further. It can be inferred that the torque of phospholipids molecule may have changed and phospholipids molecule have rearranged after PEF treatment. Moreover, as a resemblance to biological membrane structure, the phospholipid molecules of cell membrane may generate micropores after rearrangement, which result in the cell electroporation.
