Placement of Biological Membrane Patches in a Nanofluidic Gap with Control over Position and Orientation
Francesca Ruggeri, Christian Schwemmer, Mirko Stauffer +7
Purple membranes from the archaeon Halobacterium salinarum consist of two-dimensional crystals of the light-driven proton pump bacteriorhodopsin, which convert photons into a proto…
Freeform nanostructuring of hexagonal boron nitride
Nolan Lassaline, Deepankur Thureja, Thibault Chervy +4
Hexagonal boron nitride (hBN)-long-known as a thermally stable ceramic-is now available as atomically smooth, single-crystalline flakes, revolutionizing its use in optoelectronics.…
Deterministic Deposition of Nanoparticles with Sub-10 nm Resolution
Stefan Fringes, Christian Schwemmer, Colin D. Rawlings +1
Accurate deposition of nanoparticles at defined positions on a substrate is still a challenging task, because it requires simultaneously stable long-range transport and attraction…
Nanometer scale resolution, multi-channel separation of spherical particles in a rocking ratchet with increasing barrier heights
Philippe Nicollier, Christian Schwemmer, Francesca Ruggeri +3
We present a nanoparticle size-separation device based on a nanofluidic rocking Brownian motor. It features a ratchet-shaped electrostatic particle potential with increasing barrie…
Nanofluidic Rocking Brownian Motors
Michael J. Skaug, Christian Schwemmer, Stefan Fringes +2
Control and transport of nanoscale objects in fluids is challenging because of the unfavorable scaling of most interaction mechanisms to small length scales. We design energy lands…
Experimental observation of current reversal in a rocking Brownian motor
Christian Schwemmer, Stefan Fringes, Urs Duerig +2
A reversal of the particle current in rocking Brownian motors was predicted more than 20 years ago; however, an experimental verification and a deeper insight into the underlying m…
