Spanish researchers have shown that carbon nanotubes (CNTs) constitute the ideal templates for the formation of one-dimensional strings of metal nanoparticles, with potential uses as waveguides, that would allow the miniaturization of devices below the diffraction limit and as catalytic motors.
A comprehensive overview of the main concepts behind the development of nanosensors and the most relevant applications in the field of environmental analysis.
Empirical evidence suggests that China is successfully implementing its strategic plan to become a leading global force in nanotechnology.
Researchers in Switzerland have successfully integrated carbon nanotubes (CNTs) directly into a polysilicon chip. This technique is opening the way towards NEMS and CNT based system integration and the synthesis and evaluation of mechanical nano-scale transducers based on CNTs.
The properties of water, structure and dynamics, for example, are expected to change dramatically when bulk water is confined within nanotubes whose diameter is of the same order of magnitude as the size of one water molecule.
In the future hydrogen economy, hydrogen (H2) sensors will be a critical component for safety and widely needed. For example, H2 sensors will detect leaks from hydrogen-powered cars and fueling stations long before the gas becomes an explosive hazard.
A new methodology for integrating nanowires with micropatterned substrates using directed assembly and nanoscale soldering was developed by researchers at Johns Hopkins University in Baltimore. This overcomes the difficulty in making electrical contacts to nanoparticles, which so far has been a major limitation to fabricating integrated nanoelectronic devices containing large numbers of nanoparticles.
If you had brain tumor, would you rather receive your medicine through an injection in the arm or have a hole drilled in your skull? One of the most important applications of nanotechnology could be drug delivery by nanoparticles (or nanoshells) in particular into the brain. An international group of researchers developed a novel targeted nanoparticulate drug delivery system for the brain
