In a new approach to an effective 'electronic tongue' that mimics human taste, scientists in Illinois are reporting development of a small, inexpensive, lab-on-a-chip sensor that quickly and accurately identifies sweetness.
Scientists have copied the natural glue secreted by a tiny sea creature called the sandcastle worm in an effort to develop a long-sought medical adhesive needed to repair bones shattered in battlefield injuries, car crashes and other accidents.
It appears that bacteria can squeeze through practically anything. In extremely small nanoslits they take on a completely new flat shape. Even in this squashed form they continue to grow and divide at normal speeds.
Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A+M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of larger tissue constructs, such as human organs.
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.
Ein Team von der University of Bristol und dem Max-Planck-Institut fuer Kolloid- und Grenzflaechenforschung in Golm hat es jetzt erstmals geschafft, ein Protein ohne Zuhilfenahme eines Loesungsmittels zu verfluessigen.
U.S. researchers have created tiny oxygen-sensing devices made from carbon nanotubes. They say the devices demonstrate the potential application of nanotechnology in low power, wearable gas sensors and could benefit those working in confined spaces where monitoring of oxygen concentrations is essential for survival.
