摘要:	摘要： We experimentally investigate the collective dynamics in bacterial carpet microfluidic channel. The microfluidic channel is composed of single polar flagellated Vibrio alginolyticus deposited glass substrates. The individual flagellum swimming speed is tuned by varying buffer sodium concentration. Hydrodynamic coupling strength is tuned by varying buffer viscosity. The attached bacteria constantly perform two major modes in flagellum motion, namely, the local rotation and large angle flick. Particle tracking statistics shows high flagellum rotational rate and strong hydrodynamic coupling strength lead to collective sub-diffusive dynamics. The observed effect is strongly correlated to hydrodynamic coupling of flick motions between nearby bacteria. 出版者： American Institute of Physics 出版日期： 2012-05-14 出處： Applied physics letters, 2012-05, Vol.100 (20), p.203702-203702-3 資源來源： AIP Journals (American Institute of Physics) 版權： 2012 American Institute of Physics 識別號： ISSN: 0003-6951 識別號： EISSN: 1077-3118 識別號： DOI: 10.1063/1.4720072 識別號： CODEN: APPLAB
