Characterization of Electrochemical Behavior of Lecithin-Cholesterol Mixture in Formation of Model Phospholipid Membranes
Nováková, Kateřina ; Navrátil, Tomáš ; Šestáková, Ivana ; Mareček, Vladimír ; Chýlková, J.
Electrochemical behavior of lecithin-cholesterol mixture in the form of phospholipid membranes (PLMs) was studied in this contribution. Lecithin (phosphatidylcholine) and cholesterol were chosen for this research, because they are essential for living cells. Electrochemical behavior of this system was studied using an electrochemical cell developed in our laboratory and with applying electrochemical impedance spectroscopy (EIS). Different ratios between lecithin and cholesterol placed on different polycarbonate substrates were tested. The influence of time and of temperature on formation of PLMs in presence of cholesterol was investigated.
