A team of Yale scientists have demonstrated a method to understand effective synthesis of semiconductor nanowires (NWs) for both their quality and quantity, according to a report published in the journal Nanotechnology.
Graduate student Eric Stern in the department of biomedical engineering along with his colleague Guosheng Cheng, associate research scientist in electrical engineering systematically varied and tested parameters for producing GaN NWs using an optical lithographic method as a template for testing characteristics of the NWs.
A nanowire is an ultra-miniaturized cylindrical semiconductor, as small as 1 to 100 nanometers in diameter, and extending as long as a millimeter -- or 10,000 times its thickness. One nanometer is approximately a 25-millionth of an inch. GaN was chosen for these experiments as a material commonly employed in synthesis of semiconductors.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
