Abstract Scope |
We present two major developments towards the use of K. xylinus as a robotic printer of architected nanocellulose scaffolds that can be used as is or pyrolyzed to derive carbonaceous materials: 1) the use of light-induced dielectrophoresis, or the use of light fields to enable an electric field gradient, to enable spatiotemporal manipulation of K. xylinus cells; and 2) the use of a microfluidic reactor featuring microelectrodes to study how electrostimulation can potentially manipulate and influence the synthesis of BC. This second study features experiments running over fourteen days with an AC induced electric field at polarization voltages of 1 Vpp, 2 Vpp, and 5 Vpp at a frequency of 750 kHz. Results suggest that long-term BC synthesis is possible under electric fields necessary for K. xylinus manipulation. |
