Abstract

In this work, archaella of the halophilic archaeon Halobacterium salinarum are implemented as biotemplates to fabricate nanoscale cargo delivery vehicles capable of precise magnetic actuation in low-Reynolds number fluids. Mesoporous silica is deposited onto the surface of archaella using a sol-gel method to thicknesses between 400 and 900 nm, creating a porous bioinert nanostructure. Following deposition of a thin film of nickel, swimming dynamics were investigated, and a maximum average swimming velocity of a few microns per second was achieved using a low-strength uniform rotating magnetic field. The nanoswimmers are shown to efficiently navigate low-Reynolds number fluids under open loop control. This approach establishes extremophile-derived biological architectures as versatile templates for the synthesis of functional nanoscale materials and provides a facile, cost-effective method for fabrication of controllable nanoswimmers, expanding biotemplating beyond conventional bacterial systems.

生物模板化古菌纳米游泳者

在这项工作中，嗜盐古细菌盐盐杆菌的古菌被用作生物模板来制造能够在低雷诺数流体中精确磁驱动的纳米级货物运载工具。采用溶胶-凝胶法将介孔二氧化硅沉积在古菌表面，厚度在400 - 900纳米之间，形成多孔的生物惰性纳米结构。在沉积镍薄膜后，研究了游动动力学，并在低强度均匀旋转磁场下获得了每秒几微米的最大平均游动速度。在开环控制下，纳米游泳者可以有效地在低雷诺数流体中航行。该方法建立了极端微生物衍生的生物结构，作为合成功能纳米级材料的通用模板，并为制造可控纳米游泳体提供了一种简便、经济的方法，将生物模板扩展到传统的细菌系统之外。
