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…
