    Sample pre-concentration is crucial to achieve high sensitivity and low detection limits in lab-on-a-chip devices. Here, we present a system in which self-propelled catalytic micromotors are bio-functionalized and trapped ...
  • 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 ...
  • 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 ...
  • Status of eye lens radiation dose monitoring in European hospitals 

    Carinou, Eleftheria; Ginjaume Egido, Mercè; O'Connor, Una; Kopec, Renata; Sans Merce, Marta (2014-12-01)
    Article
    Restricted access - publisher's policy
    A questionnaire was developed by the members of WG12 of EURADOS in order to establish an overview of the current status of eye lens radiation dose monitoring in hospitals. The questionnaire was sent to medical physicists ...
