      We describe the propulsion mechanism of the catalytic microjet engines that are fabricated using rolled-up nanotech. Microjets have recently shown numerous potential applications in nanorobotics but currently there is a ...
    • Self-propelled micromotors for cleaning polluted water 

      Soler Turu, Lluís; Magdanz, Veronika; Fomin, Vladimir M.; Sanchez, Samuel; Schmidt, Oliver G. (2013-11-01)
      Article
      Restricted access - publisher's policy
      We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional ...
    • Thermal activation of catalytic microjets in blood samples using microfluidic chips 

      Soler Turu, Lluís; Martinez Cisneros, Cynthia; Swiersy, Anka; Sanchez, Samuel; Schmidt, Oliver G. (2013-09-10)
      Article
      Open Access
      We demonstrate that catalytic microjet engines can out-swim high complex media composed of red blood cells and serum. Despite the challenge presented by the high viscosity of the solution at room temperature, the catalytic ...
    • Trapping self-propelled micromotors with microfabricated chevron and heart-shaped chips 

      Restrepo Perez, Laura; Soler Turu, Lluís; Martinez Cisneros, Cynthia; Sanchez, Samuel; Schmidt, Oliver G. (2014-02-11)
      Article
      Open Access
      We demonstrate that catalytic micromotors can be trapped in microfluidic chips containing chevron and heart-shaped structures. Despite the challenge presented by the reduced size of the traps, microfluidic chips with ...
