Aptamers and their applications in nanomedicine

To construct ligand-directed 'active targeting' nanobased delivery systems, aptamer-equipped nanomedicines have been tested for in vitro diagnosis, in vivo imaging, targeted cancer therapy, theranostic approaches, sub-cellular molecule detection, food safety, and environmental monitoring.

Improving energy efficiency one atom at a time

Molecular beam epitaxy systems enables scientists to control the properties of new crystals with exquisite precision, right down to the atomic level. They can grow nanomaterials with features just a few billionths of a meter across, and even control how many electrons they have inside them.

Researchers synthesize material for efficient plasmonic devices in mid-infrared range

A research team has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.

Autonomous atom assembly of nanostructures using a scanning tunneling microscope

Researchers have demonstrated the autonomous computer-controlled assembly of atoms into perfect nanostructures using a low temperature scanning tunneling microscope. The results show the construction without human intervention of quantum confined two-dimensional nanostructures using single atoms or single molecules on a copper surface.
