AB  - Human serum albumin (HSA) microtubes with an interior surface composed of Pt 
      nanoparticles (PtNPs) are self-propelled in aqueous H(2) O(2) medium. They can 
      capture cyanine dye and Escherichia coli (E. coli) efficiently. Microtubes were 
      prepared by wet templating synthesis by using a track-etched polycarbonate (PC) 
      membrane with alternate filtrations of aqueous HSA, poly-l-arginine (PLA), and 
      citrate-PtNPs. Subsequent dissolution of the PC template yielded uniform hollow 
      cylinders made of (PLA/HSA)(8) PLA/PtNP stacking layers (1.16+/-0.02 mum outer 
      diameter, ca. 23 mum length). In aqueous H(2) O(2) media, the soft protein 
      microtubes are self-propelled by jetting O(2) bubbles from the open-end terminus. 
      The effects of H(2) O(2) and surfactant concentrations on the velocity were 
      investigated. The swimming microtube captured cyanine dye in the HSA component of 
      the wall. Addition of an intermediate gamma-Fe(3) O(4) layer allowed manipulation of 
      the direction of movement of the tubule by using a magnetic field. Because the 
      exterior surface is positively charged, the bubble-propelled microtubes adsorbed 
      E. coli with high efficiency. The removal ratio of E. coli by a single treatment 
      reached 99 %.
