Membrane Disk and Sphere: Controllable Mesoscopic Structures for the Capture and Release of a Targeted Object

摘要: Design of molecules for self-assembled mesoscopic structures with specific functions is an important and interesting challenge that spans across disciplines such as nanosciences. A closed lipid membrane a good example mesostructure. In this study, we developed controllable formation by making subtle change at the molecular level. We utilized synthetic photosensitive amphiphile (KAON12) to achieve photobased manipulation opening closing membranes through reversible transitions between sphere disk structures. found mechanism based on photoswitching line tension, deduced from fluctuation edge, action KAON12. Furthermore, demonstrated capture release colloidal particles into sphere. The observation Brownian motion particle confirmed encapsulation. This successful photomanipulation in noncontact manner should lead better understanding self-organization may see wider application, microreactors drug-delivery systems.
