rssNew process for obtaining alkanes from bio-oil
05-19-2009
For the protection of the environment, and because of the limited amount of fossil fuels available, renewable resources, such as specially cultivated plants, wood scraps, and other plant waste, are becoming the focus of considerable attention. Processes such as pyrolysis or liquefaction allow ...
Targeted gene suppression in cancer cells
05-12-2009
Diagnosis and treatment in one go: Korean researchers led by Tae Gwan Park and Jinwoo Cheon have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making them macroscopically and microscopically visible. As they report in the journal ...
Carbon-free fullerene analogue
05-05-2009
The discovery of a soccer-ball-shaped molecule made of 60 carbon atoms was a minor revolution in chemistry: Fullerenes are spherical, highly symmetrical molecules made of carbon atoms, and are the third form of carbon after diamond and graphite. However, the C60 "soccer ball" is not the only ...
Photoswitchable rhodamine amides for high-resolution optical 3D far-field microscopy
08-14-2007
Layer-by-layer light microscopic nanoscale images of cells and without having to prepare thin sections? A team led by Stefan Hell and Mariano Bossi at the Max Planck Intstitute for Biophysical Chemistry in Göttingen is now leading the way with a technique called optical 3D far-field ...
Manganese oxide nanoparticles as contrast agents for brain magnetic resonance imaging
05-31-2007
Magnetic resonance imaging is a very effective method for revealing anatomical details of soft tissues. Contrast agents can help to make these images even clearer and allow physiological processes to be followed in real time. Conventional gadolinium complexes currently used as MRI contrast ...
Antibody tests on fingerprints to detect drugs and diseases
05-21-2007
To this day, fingerprints are just the thing when a perpetrator needs to be arrested or a person needs to be identified. British scientists working with David A. Russell also want to make it possible to use fingerprints to reveal drug and doping transgressions and to diagnose diseases. As the ...
Ultrasensitive DNA detection with photographic paper
05-14-2007
Ultrasensitive genetic detection methods could revolutionize the diagnosis and treatment of diseases. However, all the techniques until now have been far too technically demanding for broad application. Munich researchers led by Thomas Carell have now developed a very simple method based on ...
Reasonably priced and battery-driven: a pocket PCR device
05-02-2007
A huge number of diagnostic techniques are based on PCR (the polymerase chain reaction): the use of PCR allows even the tiniest amounts of genetic material to be duplicated so that it can be analyzed. This should make things such as the rapid and reliable identification of a dangerous ...
Lily of the valley fragrance: electronic surface structure determines interactions with scent receptors
04-23-2007
An interdisciplinary team headed by Reinhold Tacke (Inorganic Chemistry, University of Würzburg), Philip Kraft (Scent Research, Givaudan Schweiz Inc.), and Hanns Hatt (Cell Biology, University of Bochum) have attempted a "scent prediction" to test their computer model of lily-of-the-valley ...
Selective binding of gold nanoparticles to the ends of rod-shaped viruses
04-10-2007
Nanotechnology appears to be an unstoppable trend and it requires defined nanoscale building blocks and patterns. "A typical difficulty with the synthesis of nanostructures is the modification of nanoscale objects at specific positions" says Alexander Bittner, whose work with a team from the ...
