摘要：

Silicon nanowires (Si-NWs) are functio-nalized with heavy meromyosin (HMM) and dispersed in aqueous solution. HMM-functionalized Si-NWs (see image) support the linear motion of actin filaments over 100-mm-long distances without any confining physical barrier. The ballistic nature of actomyosin motion on functionalized Si-NWs is qualitatively different from their diffusive motion on two-dimensional substrates. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
