Label-free detection of single biomolecules in solution has been achieved using a variety of experimental approaches over the past decade. Yet, our understanding of the magnitude of the optical contrast and its relationship to the underlying atomic s

Nanoscience aspires to mimic nature's control over functional molecular assemblies. Here we present a templating technique for the efficient attachment of two different oligonucleotides to a homobifunctional molecule, enabling its controlled and prog

Within the field of DNA nanotechnology, numerous methods were developed to produce complex two- and three-dimensional DNA nanostructures for many different emerging applications. These structures typically suffer from a low tolerance against non-opti

Recently introduced DNA nanomolds allow the shape-controlled growth of metallic nanoparticles. Here we demonstrate that this approach can be used to fabricate longer linear metal nanostructures of controlled lengths and patterns. To this end, we esta

We report the design and assembly of chiral DNA nanotubes with well-defined and addressable inside and outside surfaces. We demonstrate that the outside surface can be functionalised with a chiral arrangement of gold nanoparticles to create a plasmon

We introduce a new concept for the solution-based fabrication of conductive gold nanowires using DNA templates. To this end, we employ DNA nanomolds, inside which electroless gold deposition is initiated by site-specific attached seeds. Using program

We introduce a new concept that allows the synthesis of inorganic nanoparticles with programmable shape. Three-dimensional DNA origami nanostructures harboring an internal cavity are used as molds. A small gold nanoparticle within the cavity nucleate
