DNA-assembled nanoarchitectures with multiple components in regulated and coordinated motion
Pengfei Zhan, Maximilian J. Urban, Steffen Both +4
Coordinating functional parts to operate in concert is essential for machinery. In gear trains, meshed gears are compactly interlocked, working together to impose rotation or trans…
DNA-Assembled Multilayer Sliding Nanosystems
Pengfei Zhan, Steffen Both, Thomas Weiss +1
DNA nanotechnology allows for the realization of complex nanoarchitectures in which the spatial arrangements of different constituents and most functions can be enabled by DNA. Whe…
Watching a Single Fluorophore Molecule Walk into a Plasmonic Hotspot
Ling Xin, Mo Lu, Steffen Both +7
Plasmonic nanoantennas allow for enhancing the spontaneous emission, altering the emission polarization, and shaping the radiation pattern of quantum emitters. A critical challenge…
Gold nanocrystal-mediated sliding of doublet DNA origami filaments
Maximilian J. Urban, Steffen Both, Chao Zhou +4
Sliding is one of the fundamental mechanical movements in machinery. In macroscopic systems, double-rack pinion machines employ gears to slide two linear tracks along opposite dire…
First-order perturbation theory for material changes in the surrounding of open optical resonators
Steffen Both, Thomas Weiss
The single-mode approximation of the resonant state expansion has proven to give accurate first-order approximations of resonance shifts and linewidth changes when modifying the ma…
