- ItemStimuli‐responsive microjets with reconfigurable shape(Hoboken, NJ : Wiley, 2014) Magdanz, Veronika; Stoychev, Georgi; Ionov, Leonid; Sanchez, Samuel; Schmidt, Oliver.G.Flexible thermoresponsive polymeric microjets are formed by the self‐folding of polymeric layers containing a thin Pt film used as catalyst for self‐propulsion in solutions containing hydrogen peroxide. The flexible microjets can reversibly fold and unfold in an accurate manner by applying changes in temperature to the solution in which they are immersed. This effect allows microjets to rapidly start and stop multiple times by controlling the radius of curvature of the microjet. This work opens many possibilities in the field of artificial nanodevices, for fundamental studies on self‐propulsion at the microscale, and also for biorelated applications.
- ItemChemotactic behavior of catalytic motors in microfluidic channels(Hoboken, NJ : Wiley, 2013) Baraban, Larysa; Harazim, Stefan M.; Sanchez, Samuel; Schmidt, Oliver.G.Chemotaxis in practice: Two different artificial catalytic micromotors (tubular and spherical, see scheme) show chemotactic behavior in microfluidic channels demonstrating that catalytic micromotors can sense the gradient of chemical fuel in their environment and be directed towards desired locations.
