Optical Voltage Sensing Using DNA Origami
We explore the potential of DNA nanotechnology for developing novel optical voltage sensing nanodevices that convert a local change of electric potential into optical signals. As a proof-of-concept of the sensing mechanism, we assembled voltage responsive DNA origami structures labeled with a single pair of FRET dyes. The DNA structures were reversibly immobilized on a nanocapillary tip and und...
متن کاملTunable optical activity of plasmonic dimers assembled by DNA origami.
We investigate the optical response of gold nanorod (AuNR) dimers assembled in parallel on a DNA origami template. Plasmonic circular dichroism (CD) was found to be highly dependent on the orientation of the dimers relative to the DNA axis and the inter-rod distances. Dipole-dipole distances play a critical role in the induced plasmonic chirality. The orientation dependence of induced CD was fu...
متن کاملRobotic Origami Folding Robotic Origami Folding
Origami, the art of paper sculpture, is a fresh challenge for the field of robotic manipulation, and provides a concrete example of the many difficulties and general manipulation problems faced in robotics. This paper describes our initial exploration, and highlights key problems in the manipulation, modeling, and design of foldable structures. Results include the design of the first origami-fo...
متن کاملSymplectic Origami
An origami manifold is a manifold equipped with a closed 2-form which is symplectic except on a hypersurface where it is like the pullback of a symplectic form by a folding map and its kernel fibrates with oriented circle fibers over a compact base. We can move back and forth between origami and symplectic manifolds using cutting (unfolding) and radial blow-up (folding), modulo compatibility co...
متن کاملOrigami World
We paste together patches of AdS6 to find solutions which describe two 4-branes intersecting on a 3-brane with non-zero tension. We construct explicitly brane arrays with Minkowski, de Sitter and Anti-de Sitter geometries intrinsic to the 3-brane, and describe how to generalize these solutions to the case of AdS4+n, n > 2, where n n + 2-branes intersect on a 3-brane. The Minkowski and de Sitter...
