Automated imaging of cells in developing plants is described in a paper published this week in Nature Methods. These methods will permit a more detailed understanding of the cellular behaviors that underlie plant growth and development.
As part of its ongoing series of live webinars on AFM technology and advancements, Veeco Instruments Inc. will be hosting a free online seminar on 'Atomic Force Microscopy: Characterizing Biomaterials at the Nanoscale'.
One property of gold nanoparticles stands in the way of many nanotechnological developments: They're sticky. Gold nanoparticles can be engineered to attract specific biomolecules, but they also stick to many other unintended particles - often making them inefficient at their designated task. MIT researchers have found a way to turn this drawback into an advantage.
Damit die Dosis eines Medikaments kuenftig so niedrig wie therapeutisch moeglich gehalten werden kann, sollen die Wirkstoffe in Zukunft direkt zum Zielort im Organismus transportiert und dort erst freigesetzt werden. Dafuer sollen sie in Nanopartikel eingeschlossen werden, die ihre Fracht nur bei einem bestimmten pH-Wert, einer definierten Temperatur oder unter anderen spezifischen Bedingungen freigeben.
The loss of electrical resistance of a metal particle is also a matter of its size. A group of researchers has now proven that the temperature below which a material becomes a superconductor can increase dramatically, when the material is present as spherical nanoparticles.
With controlled stretching of molecules, Cornell researchers have demonstrated that single-molecule devices can serve as powerful new tools for fundamental science experiments. Their work has resulted in detailed tests of long-existing theories on how electrons interact at the nanoscale.
Physicists in Europe have successfully glimpsed the motion of electrons in molecules. The results are a major boon for the research world. Knowing how electrons move within molecules will facilitate observations and fuel our understanding of chemical reactions.
The University of Glasgow is playing a key role in a 26M Euro European project called MODERN looking at how to design the next generation computer chips - using variable and unreliable nanotransistors.
