Dielectrophoretic Trapping of DNA Origami
Small, 2008In this thesis three-dimensional tube-shaped DNA-origamis were dielectrophoretically trapped within lithographically fabricated nanoelectrodes. The origamis had been premade while the electrodes were fabricated specifically for these experiments with two different gapsizes, 150 nm and 400 nm.

Protein Coating of DNA Origami
2023DNA origami has emerged as a common technique to create custom two- (2D) and three-dimensional (3D) structures at the nanoscale. These DNA nanostructures have already proven useful in development of many biotechnological tools; however, there are still challenges that cast a shadow over the otherwise bright future of biomedical uses of these DNA ...

Biosensors and Bioelectronics, 2019
Traditional analytical techniques face many limitations such as time-consuming process, complicated sample preparation, high consumption of reagents and need for expensive equipment. So, it is important that simple, rapid and sensitive detection methods are introduced.

Cellular Uptake of DNA Origami
2023This chapter discusses the methods involved in achieving and analyzing cellular uptake of DNA origami. While cells naturally internalize substances from their surroundings, more than a simple addition of DNA origami in the surrounding cell medium is necessary to ensure DNA origami particles successfully enter the intracellular environment.

Parallel Functionalization of DNA Origami
2023DNA origami enables the creation of large supramolecular structures, with precisely defined features at the nanoscale. The concept thus naturally lends itself to the concept of molecular patterning, i.e., the positioning of molecular moieties and functional features. Creation of nanoscale patterns was already disseminated by Rothemund in 2006, in which

Nano Letters, 2014
Structural DNA nanotechnology, and specifically scaffolded DNA origami, is rapidly developing as a versatile method for bottom-up fabrication of novel nanometer-scale materials and devices. However, lengths of conventional single-stranded scaffolds, for example, 7,249-nucleotide circular genomic DNA from the M13mp18 phage, limit the scales of these ...

A primer to scaffolded DNA origami
Nature Methods, 2011Molecular self-assembly with scaffolded DNA origami enables building custom-shaped nanometer-scale objects with molecular weights in the megadalton regime. Here we provide a practical guide for design and assembly of scaffolded DNA origami objects. We also introduce a computational tool for predicting the structure of DNA origami objects and provide ...

Probing the Security of DNA Origami
2018 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2018DNA origami is a method used to program the self-assembly of nanoscale computational systems. The contribution of this paper is to probe the security of a canonical DNA origami that is often reused. The paper describes the techniques we used to design probes whose input targets the origami systems' integrity.

DNA-nanostrukturer giver nye muligheder for studier af individuelle molekyler. Ved at udnytte DNAs unikke selvsamlende egenskaber kan man designe systemer, hvorpå der kan studeres kemiske reaktioner, fluoroforer og biiomolekyler på enkeltmolekyle-niveau.
