Japanese scientists report on a new biosensing protocol based on monitoring changes in optical transmittance of a solution containing self-assembled chains of functionalized magnetic beads being rotated by an external magnetic field.
From innovations that enable improved health care and clean energy technologies, to the advent of exciting video games and new crime-solving techniques, the growing impact of nanotechnology on society will take center stage when the College of Nanoscale Science and Engineering of the University at Albany holds its third annual celebration of 'NANOvember'.
Selbstorganisationsprozesse chemischer Bausteine sind die Basis fuer viele biologische Vorgaenge, zunehmend stossen sie auch auf Interesse im Bereich der Materialsynthese. Beispielsweise um hochgeordnete Nanokomposite oder hochporoese Materialien mit besonderen Eigenschaften herzustellen. Forscher stellen nun einen neuartigen, sehr vielseitigen Ansatz vor, mit dem die Synthese einer neuen Familie bioorganisch-anorganischer Nanoverbundmaterialien im grossen Massstab gelingt - mit bisher unerreichter Kontrolle ueber die Beschaffenheit und Struktur der Produkte.
If you say 'synchrotron' to most scientists, they will picture an immense, highly expensive and rather rare facility designed to produce highly intense beams of light, such as the UK's Diamond Light Source that boasts a 500 metre circumference and cost GBP 263 million (EUR 297 million) to build. However, that could soon change, as EU-funded scientists have created a table-top device capable of producing synchrotron X-rays that are as intense as those produced by some of the world's largest X-ray facilities.
Scientists at Helmholtz-Zentrum Berlin (HZB) have developed a method that uses the magnetic fingerprint of the charge-carrying particles to reveal exactly how electricity is being lost. They did so by cleverly manipulating the magnetic properties of these particles.
Proteins are an interesting class of drugs because they demonstrate high biological activity and are highly specific in their effects. It has become possible to produce more and more proteins with tailored pharmacological properties; however transport and controlled release of the protein drugs in the body have remained a challenge. Researchers have now introduced an alternative to the usual transport agents, such as liposomes: by using a simple, inexpensive, gentle process, they were able to produce pure protein microspheres of uniform size.
Purdue University and the University of Notre Dame are teaming up with state officials to offer Indiana's first business plan competition targeting startup ventures and emerging companies in nanotechnology.
Researchers have experimentally investigated a Landau-Zener scenario in a system of one-dimensional quantum gases in two coupled potential tubes. They found that the collective tunneling of the many particles is drastically altered from the single-particle case, ultimately leading to a breakdown of the transfer to the opposite side.
Einem internationalen Forscherteam ist es erstmals gelungen, die Entstehung von Aluminiumoxid-Nanodraehten in atomarer Aufloesung und in Echtzeit zu beobachten. Dabei stellten die Wissenschaftler fest, dass das selbstkatalytische Wachstum der Aluminiumoxid-Draehte in einem zweistufigen Prozess erfolgt, wobei der Draht entlang seiner Laengsachse Lage fuer Lage aufgebaut wird.
