摘要

本文展示了一种在低雷诺数流体环境中迁移的微生物机器人，该机器人由可移动的鞭毛细菌提供动力。为了对鞭毛菌进行强力固定化，我们利用了由木糖醋酸杆菌产生的细菌纤维素(BC)。我们使用微流控剪切装置评估了BC与鞭毛菌fischeri alivibrio之间的粘附性，并证实了BC优于传统MEMS材料。在氧浓度梯度的作用下，木酸糖醋杆菌在锥形微孔中产生了锥形BC。成功地将a . fischeri固定在BC结构上，形成了一个微生物机器人，该机器人在培养基中以4.8 μm/s的平均速度游动。

A self-swimming microbial-robot using microfabricated biopolymer

This paper demonstrates a microbial-robot that migrates in low Reynolds number fluidic environments powered by motile flagellated bacteria. To immobilize the flagellated bacteria strongly, we utilized bacterial cellulose (BC), which was produced by Gluconacetobacter xylinus. We evaluated the adhesion between the BC and the flagellated bacteria, Aliivibrio fischeri using a microfluidic shear device and confirmed that the superiority of BC over conventional MEMS materials. Conical-shaped BC was produced by Gluconacetobacter xylinus in conical microholes with a help of oxygen concentration gradient. A. fischeri were successfully immobilized onto the BC structure to form a microbial-robot, which could swim in culture media at an average speed of 4.8 μm/s.
