我们描述了悬浮在向列型液晶中的游动细菌对非运动真核细胞和聚合物微粒的受控运输和递送。细菌在一个稳定的单向路径(或沿着一个复杂的图案化导向场)上推动可逆附着的货物,距离非常长。游泳速度的数值模拟和分析预测提供了一个机械的洞察系统的流体动力学。本研究为利用货物携带细菌在工程应用和了解物种间的相互作用,在多微生物群落奠定了基础。
We describe the controlled transport and delivery of non-motile eukaryotic cells and polymer microparticles by swimming bacteria suspended in nematic liquid crystals. The bacteria push reversibly attached cargo in a stable, unidirectional path (or along a complex patterned director field) over exceptionally long distances. Numerical simulations and analytical predictions for swimming speeds provide a mechanistic insight into the hydrodynamics of the system. This study lays the foundation for using cargo-carrying bacteria in engineering applications and for understanding interspecies interactions in polymicrobial communities.
