Electromagnetically controlled biological assembly of aligned bacterial cellulose nanofibers. Sano, M. B., Rojas, A. D., Gatenholm, P., & Davalos, R. V. Ann Biomed Eng, 38(8):2475-84, 2010. 1573-9686 Sano, Michael B Rojas, Andrea D Gatenholm, Paul Davalos, Rafael V Journal Article Research Support, Non-U.S. Gov't United States 2010/03/20 Ann Biomed Eng. 2010 Aug;38(8):2475-84. doi: 10.1007/s10439-010-9999-0. Epub 2010 Mar 19.doi abstract bibtex We have developed a new biofabrication process in which the precise control of bacterial motion is used to fabricate customizable networks of cellulose nanofibrils. This article describes how the motion of Acetobacter xylinum can be controlled by electric fields while the bacteria simultaneously produce nanocellulose, resulting in networks with aligned fibers. Since the electrolysis of water due to the application of electric fields produces the oxygen in the culture media far from the liquid-air boundary, aerobic cellulose production in 3D structures is readily achievable. Five separate sets of experiments were conducted to demonstrate the assembly of nanocellulose by A. xylinum in the presence of electric fields in micro- and macro-environments. This study demonstrates a new concept of bottom up material synthesis by the control of a biological assembly process.
