Adhesion signals of phospholipid vesicles at the electrified interface

Adhesion signals of individual phospholipid vesicles appear due to the double-layer charge displacement tracing vesicle transformation to a film of a finite surface area [1-3]. The key ingredient in amperometric measurement is the versatile potentiostatic control of adhesion forces by changing the surface charge and tension at the electrode/aqueous electrolyte interface. The adhesion force can be fine-tuned to study the interplay of complex processes involved in a deformable particle-electrode double-layer interactions. Our aim is to demonstrate that adhesion based detection is sensitive to polar head groups in phospholipid vesicles formed from phosphatidylcholine (PC) and phosphatidylserine (PS) lipid.
