Self-assembly of precisely defined DNA nanotube superstructures using DNA origami seeds
We demonstrate a versatile process for assembling micron-scale filament architectures by controlling where DNA tile nanotubes nucleate on DNA origami assemblies. "Nunchucks," potential mechanical magnifiers of nanoscale dynamics consisting of two nanotubes connected by a dsDNA linker, form at yields sufficient for application and consistent with models
Review: The increasing importance of carbon nanotubes and nanostructured conducting polymers in biosensors
The growing need for analytical devices requiring smaller sample volumes, decreased power consumption and improved performance have been driving forces behind the rapid growth in nanomaterials research. Due to their dimensions, nanostructured materials display unique properties not traditionally observed in bulk materials. Characteristics such as increased surface area along with enhanced electrical/optical properties make them suitable for numerous applications such as nanoelectronics, photovoltaics and chemical/biological sensing. In this review we examine the potential that exists to use nanostructured materials for biosensor devices. By incorporating nanomaterials, it is possible to achieve enhanced sensitivity, improved response time and smaller size. Here we report some of the success that has been achieved in this area. Many nanoparticle and nanofibre geometries are particularly relevant, but in this paper we specifically focus on organic nanostructures, reviewing conducting polymer nanostructures and carbon nanotubes
Use of a copolymer dressing on superficial and partial-thickness burns in a paediatric population
Molecular induced field effect in superconducting
The study of the effect of self-assembled organic monolayers on the critical
current in thin superconducting Nb films is presented. Correlation is found
between the coverage of the adsorbed layer and the critical current. A large
change of up to 50% in the critical current by the well-organized
monolayers is observed. The phenomenon is explained by the adsorption-induced electric field effect diminishing the surface pinning force
