Multifunctional nanotechnology tool simplifies design and study of nanostructures

Basic operations in the field of nanotechnology that are currently very difficult or impossible to perform can become easy with a new multi-nano tool called FIBLYS. Nanosized components in for example solar cells will be designed and studied in an entirely new way, which the researchers hope will increase the solar cells' energy output with up to 15 percent.

Artificial cilia spur new thinking in nanotechnology (w/video)

Due to the importance of ciliary functions for health, there is great interest in understanding the mechanism that controls the cilias' beating patterns. But learning exactly how cilia movement is coordinated has been challenging. That may be beginning to change as a result of the creation, by a team of Brandeis researchers, of artificial cilia-like structures that dramatically offers a new approach for cilia study.

Got flow cytometry? All you need is five bucks and a cell phone

Researchers at the BioPhotonics Laboratory at the UCLA Henry Samueli School of Engineering and Applied Science have developed a compact, lightweight and cost-effective optofluidic platform that integrates imaging cytometry and florescent microscopy and can be attached to a cell phone. The resulting device can be used to rapidly image bodily fluids for cell counts or cell analysis.

Nanotechnology for a Viagra patch

Sildenafil citrate, commonly known as Viagra, is currently the first choice drug for erectile dysfunction but despite its success oral delivery of the drug is hampered by numerous side effects, the long delay before it starts working and the short amount of time it lasts. Researchers in Egypt think they may have a solution via nanotechnology.

Storing quantum information permanently

Storing quantum information correctly and permanently has not been possible thus far. The latest studies show that topological memory harbours great potential in this respect - but only if the interferences that eventuate stay put instead of spreading.

Biological nanowire interface using piezotronics

Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry.

Nanosensor detects minute traces of plastic explosives

Working in collaboration with the RhineMain Polytechnic, materials scientists at the TU Darmstadt have developed an extremely sensitive explosives sensor that is capable of detecting even slight traces of the high-explosive chemical compound pentaerythritol tetranitrate (PETN). Terrorists had employed PETN in several attacks on commercial aircraft.

Nano-Sensor erkennt kleinste Mengen Plastiksprengstoff

Materialwissenschaftler der TU Darmstadt haben in Zusammenarbeit mit der Hochschule RheinMain einen ausserordentlich sensiblen Sprengstoffsensor entwickelt. Dieser kann geringste Spuren der hochexplosiven Chemikalie Pentaerythrityltetranitrat (PETN) nachweisen. Terroristen hatten PETN bei mehreren Anschlagsversuchen auf Flugzeuge eingesetzt.

Nachschlagwerk der Lichtwerkzeuge

Prof. Dr. Juergen Popp und Prof. Dr. Stefan Heinemann von der Uni Jena haben den ersten Teil eines umfassenden Handbuchs zur Biophotonik herausgebracht. Das Handbook of Biophotonics Bd. 1 erklaert die naturwissenschaftlichen Grundlagen der Licht-Materie-Interaktion und soll so die Zusammenarbeit von verschiedenen wissenschaftlichen Disziplinen in der Biophotonik erleichtern.
