Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes.
The Engineering and Physical Sciences Research Council (EPSRC) and the Technology Strategy Board are investing up to £2.5 million in feasibility studies to accelerate commercial applications in the novel material, graphene. It will include related carbon-based, two-dimensional nanotechnologies that have recently emerged from the science base.
Physikern der Leibniz Universitšt Hannover ist es nun in Kooperation mit amerikanischen Wissenschaftlern erstmals gelungen, ballistischen Nanostrukturen in definierter Weise herzustellen und umfassend zu charakterisieren.
Gone are the goofy glasses required of existing sets. Instead, assistant professor Jayan Thomas is working on creating the materials necessary to create a 3-D image that could be seen from 360 degrees with no extra equipment.
Nanomotors have been controlled inside living cells for the first time, report a team of chemists and engineers at Penn State University. The scientists placed tiny rocket-shaped synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically to spin and to battering against the cell membrane.
Researchers have studied the surface chemistry of ruthenium nanoparticles (Ru NPs) by using GC, IR, solid-state, and gas-phase NMR spectroscopy. They have also characterized the nanoparticles by wide-angle X-ray scattering (WAXS) and X-ray photoelectron spectroscopy (XPS) analysis.
A technique which may one day be used for tumor therapy and imaging could be greatly improved thanks to new insights obtained by scientists from the University of Twente, the Erasmus MC and the TU Delft.
Due to the particular uncertainties concerning evaluation of the possible risks of nanomaterials for human health and the environment, the German Federal Environment Agency (Umweltbundesamt) supports the establishment of a European register of products containing nanomaterials as a precautionary measure.
