Large-scale fabrication of integrated nanoelectronic devices moves closer

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.

Nanocarriers could become an alternative to brain surgery

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

One step closer to industrial fabrication of photonic crystal devices

Researchers in the UK and Germany told Nanowerk that they developed a simple, fast and efficient method for fabricating metallic photonic crystals. This new method opens the door to a number of applications in telecommunication, all-optical switching, sensors, and semiconductor devices.

Nanowires could lead to improved solar cells

With an increased focus on alternative sources of cheap, abundant, clean energy, solar cells are receiving lots of attention. The dye sensitized solar cell (DSSC) is one of the most important developments in photovoltaics in the last two decades. Researchers are now on the brink of improving the efficiency of DSSC through nanowires.
