Zusammenfassung:This letter describes the control of molecular filament organization through biologically inspired intermediates, enabling us to obtain large-area regular nanopatterns. We first studied cultured single filamentous actins on an unmodified glass surface (hydrophilic surface) and introduced myosin-II to modify the control. We then utilized an inorganic salt crystallization approach on the response of these two proteins, actin filament and myosin-II, to analyze the resultant spatially localized patterns. Through the utilization of myosin-II and the salt crystallization approach, we were able to induce the filament orientation of 63°; while without myosin-II, we induced an orientation of 90°.
