Description:
We report the incrementally staged design, synthesis, characterization, and operation of a molecular machine that behaves like a nanoscale elevator. The operation of this device, which is made of a platformlike component interlocked with a trifurcated riglike component and is only 3.5 nanometers by 2.5 nanometers in size, relies on the integration of several structural and functional molecular subunits. This molecular elevator is considerably more complex and better organized than previously reported artificial molecular machines. It exhibits a clear-cut on-off reversible behavior, and it could develop forces up to around 200 piconewtons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Badjic, Jovica D -- Balzani, Vincenzo -- Credi, Alberto -- Silvi, Serena -- Stoddart, J Fraser -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1845-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉California NanoSystems Institute and Department of Chemistry and Biochemistry, University of California, Los Angeles, 405 Hilgard Avenue, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15031499" target="_blank"〉PubMed〈/a〉
