Understanding the impact of nanomaterials on human health will require more detailed knowledge about the protein corona that surrounds nanoparticles in biological environments.
Graphene nanoribbons with low defect densities and large energy gaps can be fabricated by chemically unzipping carbon nanotubes and annealing the result.
Contacts between a single molecule and a metal electrode can be good or bad depending on the number of metal atoms that are in direct contact with the molecule.
The extracellular matrix is a nanocomposite material that supports the attachment of cells and provides information for tissue development. This Review outlines the architecture of this matrix, how nanotechnological approaches can be used to recreate its structure for developing better tissue and organ substitutes, and the challenges and future prospects of applying nanotechnology in tissue engineering.
Can silicon ever be a true direct-bandgap semiconductor? The first observation of a new, short-lived photoluminescence band from silicon nanocrystals offers fresh hope.
RNA can be designed and manipulated to form well-defined structures with useful functions. This article reviews the synthesis of RNA nanoparticles, the applications of such nanoparticles in nanomedicine, and future challenges for the field of RNA nanotechnology.
Solutions of DNA-based molecules can be taught to play a simple game in a process that does not require the operator to be familiar with the underlying molecular programming.
An atomic force microscope with antibodies attached to its tip can be used to determine methylation patterns in individual DNA strands by making hundreds of force spectroscopy measurements.
Ideas about angular momentum that have been borrowed from optics could allow the magnetic and spin structures of materials to be studied on atomic scales with electron vortex beams.
Samples of graphene supported on boron nitride demonstrate superior electrical properties, achieving levels of performance that are comparable to those observed with suspended samples.
Arrays of graphene nanoribbons are fabricated on structured silicon carbide substrates using self-organized growth, without lithography and with well-controlled widths.
