Circular Dichroism of Chiral Molecules in DNA- Assembled Plasmonic Hotspots

Luisa M. Kneer, Eva-Maria Roller, Lucas V. Besteiro +3

The chiral state of a molecule plays a crucial role in molecular recognition and biochemical reactions. Because of this and owing to the fact that most modern drugs are chiral, the…

Tunable dynamics of flexible magnetic microcrosses: synchronous rotation, breathing and out-of-plane arm overtaking

Joseph Tavacoli, Andris P. Stikuts, Mihir Dass +2

We combine colloidal self-assembly and soft-lithography techniques to realize flexible magnetic microcrosses that can be manipulated via external, time dependent magnetic fields. T…

Chiral plasmonic nanocrystals for generation of hot electrons: towards polarization-sensitive photochemistry

Tianji Liu, Lucas V. Besteiro, Tim Liedl +3

The use of biomaterials - with techniques such as DNA-directed assembly or bio-directed synthesis - can surpass top-down fabrication techniques in creating plasmonic superstructure…

Fabrication of functional 3D nanoarchitectures via atomic layer deposition on DNA origami crystals

Arthur Ermatov, Melisande Kost, Xin Yin +6

While DNA origami is a powerful bottom-up fabrication technique, the physical and chemical stability of DNA nanostructures is generally limited to aqueous buffer conditions. Wet ch…

Controlling the size and adhesion of DNA droplets using surface-active DNA molecules

Daqian Gao, Sam Wilken, Anna Nguyen +3

Liquid droplets of biomolecules serve as organizers of the cellular interior and are of interest in biosensing and biomaterials applications. Here, we investigate means to tune the…
