title: Dry micromanipulation of supramolecular giant vesicles on a silicon substrate: highly stable hydrogen-bond-directed nanosheet membrane.
abstract: Guanosine derivative 1 forms hydrogen-bond-directed giant vesicles. On a silicon substrate, the vesicles retain their shape and internal water phase even after removal of external water under vacuum. Dry manipulation of the micrometer-sized vesicles was carried out via AFM-tip-induced partition and fusion of the vesicles. For larger vesicles (5-10 μm), external solutions were successfully injected through a microcapillary inserted into the vesicle in air.
