|a We report on a new approach to direct the immobilization of unilamellar lipid vesicles on substrate-supported lipid bilayers in a spatially confined manner. The adsorption of vesicles from solution is limited to areas of disorder in the bilayers, which is induced by scanning a pattern in situ with an atomic force microscopy (AFM) tip using high imaging forces. Lines of vesicles with a length exceeding 25 microm and a width corresponding to that of a single surface-immobilized vesicle have been fabricated. The adsorbed vesicles are effectively immobilized and do not desorb spontaneously. However, AFM with forces of several nanoNewtons allows one to displace vesicles selectively. The novel methodology described, which may serve as a platform for research on proteins incorporated in the lipid bilayers comprising the vesicles, does not require chemical labeling of the vesicles to guide their deposition
