Researchers describe a new type of molecule that activates so-called voltage-gated potassium channels when exposed to light of a certain color. These molecules could have therapeutic potential in the treatment of some forms of blindness and other diseases.
Auf einer Flaeche von 2400 Quadratmetern bietet das ZNT eine flexible, interdisziplinaere und interaktive Plattform fuer aktuelle Themen aus Naturwissenschaft und Technik. Rund um die Dauerausstellung zur Nano- und Biotechnologie gruppieren sich Praesentationen der Partner aus Industrie, Wissenschaft und Forschung, ein Veranstaltungsforum, Sonderausstellungen zu neuen Materialien, Robotik und Wellenkraftwerken.
Searching for biomarkers that can warn of diseases such as cancer while they are still in their earliest stage is likely to become far easier thanks to an innovative biosensor chip developed by Stanford University researchers.
A team of Northwestern University researchers, using an extremely sensitive nanotechnology-based tool known as the biobarcode system, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy.
Researchers at Washington University in St. Louis have developed a polymer-coated gold nanocage that not only opens in response to light to release a small amount of a drug payload, but then closes when the light is turned off, leaving this nanodevice ready to deliver another dose of drug on command.
New research makes it possible to scrutinize activities that occur over hours or even days inside cells, potentially solving many of the mysteries associated with molecular-scale events occurring in these tiny living things.
Understanding the electrical properties of graphene is important because, unlike the other materials used by the electronics industry, it remains stable and conductive down to the molecular scale. As a result, when the current silicon technology reaches it's a fundamental miniaturization limit in coming years, graphene could very well take its place.
The Energy Sciences Building (ESB) will provide an environment that will accelerate the pace of discovery by bringing together interdisciplinary teams of researchers in a space that can be adjusted to accommodate an evolving energy-related science agenda. Construction is scheduled to begin during fiscal year 2011.
Known as a cryo-scanning electron microscope, the device is capable of examining single cells or even single molecules and will be used to help researchers within the Multidisciplinary Nanotechnology Centre (MNC) carry out high level research and development in a range of sectors from healthcare and steel to printed electronics and solar cells.
