Self-assembled physical unclonable function labels based on plasmonic coupling
Mihir Dass, Lena Raab, Christoph Pauer +7
Counterfeiting threatens human health, social equity, national security and global and local economies. Hardware-based cryptography that exploits physical unclonable functions (PUF…
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…
