Silicon nanocrystals map location of spreading tumors

Nano-sized fluorescent particles known as quantum dots have shown promise as powerful imaging agents capable of detecting a wide range of diseases, but these nanoparticles are usually made with toxic metals such as cadmium. Now, researchers at the University of Buffalo have developed a novel synthetic method that enables them to design and create biocompatible fluorescent nanocrystals made of non-toxic silicon.

Nanotechnology's contribution to reconstructive surgery

To rebuild damaged parts of a human body from scratch is a dream that has long fired human imagination, from Mary Shelley's Doctor Frankenstein to modern day surgeons. Now, a team of European scientists, working in the frame of the EUREKA project ModPolEUV, has made a promising contribution to reconstructive surgery thanks to an original multidisciplinary approach matching cutting-edge medicine to the latest developments in nanotechnology.

Butterfly wings behind anti-counterfeiting nanotechnology

Imagine a hole so small that air can't go through it, or a hole so small it can trap a single wavelength of light. Nanotech Security Corp., with the help of Simon Fraser University researchers, is using this type of nanotechnology to create unique anti-counterfeiting security features.

Electron gas on the surface of an insulator opens the way to multifunctional transistors

Researchers at CNRS and Universite Paris-Sud 11 have succeeded in creating a conductive layer on the surface of strontium titanate (SrTiO3), a transparent insulating material considered to be very promising for the development of future microelectronics applications. Two nanometers thick, this conductive layer is a two-dimensional metallic electron gas (2DEG) that is part of the insulating material.
