A new process allows growing carbon nanotubes directly onto MEMS

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.

Understanding the role of carbon nanotubes as water carriers

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, nanotech-based H2 sensors will be widely needed

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.

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

Hybrid carbon nanotube material allows ultrafast nonlinear optical switching

Nano Zinc Oxide (ZnO) and Carbon Nanotubes (CNTs) are arguably two of the most studied nanomaterials in recent years. Combining these two nanomaterials into hybrid nanomaterial presents a fascinating nanosystem for further investigations.

Nanoscopic medicine: the emergence of a new medical specialty

Nanoscopic medicine refers to the direct visualization, analysis (diagnosis) and modification (therapy) of nanoscopic protein machines in life cells and tissues with the aim to improve human health.

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.
