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.

Silicon-Nested Gadonanotubes Promise Big Advance for Medical Imaging

A porous, disk-shaped “nest” for nanotubes may help magnetic resonance imaging become better than ever at finding evidence of cancer if the results of research led by investigators at Rice University are any indication of future success. The researchers, whose work was published in the journal Nature Nanotechnology, have developed a general method for trapping [...]

Electron gas on insulator’s surface opens way to multifunctional transistors

French researchers 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. Easy to produce, [...]

Mapping Tumor Heterogeneity With Quantum Dots

A research team from Emory University has developed a method for mapping the molecular heterogeneity of human prostate tumor biopsies obtained from cancer patients using a mixture of four quantum dots linked to antibodies that can detect cancer-associated proteins. Shuming Nie, the principal investigator of the Emory University and Georgia Institute of Technology Center of [...]
