제목 Interactions between Charged Vesicles
초록 We measured the interactions between charged vesicles by using newly developed “optical bottle”. When a laser beam is applied to the small unilamellar vesicles, the radial forces are exerted on them via optical pressure, thus concentrating vesicles toward the beam center. We compute interaction parameter—virial coeffeicient (B2)—by measuring concentrations before and after applying the optical force. We measure interactions of liposomes with different surface charge density controlled by the ratio of charged lipids (DOPG) and neutral lipids (DOPC). Static light scattering experiments were also performed to validate optical bottle techniques.
