Researchers have created a surface that can align liquid-crystal molecules, enabling the construction of LCDs and opening up the possibility of biosensors. The aligned liquid crystals can detect the presence of certain types of DNA without additional equipment.
Purdue researchers develop a new optical biosensor that can detect minute quantities of Listeria monocytogenes in less than 24 hours. The sensor is selective enough to recognize only the species monocytogenes and has improved detection capabilities compared to existing commercial test kits.
The von Liebig Center has awarded six grants totaling $1.2 million to UC San Diego faculty for commercializing their research. These grants support projects in various fields, including bioengineering, computer science and engineering, electrical and computer engineering, and mechanical aerospace engineering.
Researchers have discovered an imaging technique that monitors cancer cell proliferation by incorporating fluorescent proteins into cell nuclei. The technique allows for simultaneous observation of up to 100 cells and can be used to screen compound libraries for novel anti-cancer therapies.
The UGA team will expand on their glancing angle deposition technique to fabricate nanoscale 3-D pillars, providing unique features for biosensing applications. The project aims to solve pressing health-related problems through interdisciplinary research and cooperation.
Researchers at University of Illinois have developed a highly sensitive and selective biosensor that uses DNA-gold nanoparticle chemistry to detect lead and other metal ions. The colorimetric sensor can be tuned for different contaminant concentrations, making it suitable for on-site detection.
Researchers from the University of Delaware have developed a cheap and disposable biosensor using gold-on-plastic technology, which can detect targeted molecules in bodily fluids with high accuracy. The device is more specific than existing methods, such as latex agglutination tests, and can be produced at a lower cost.
A portable, hand-held biosensor has been developed to detect a wide range of medically important chemical compounds. The device, capable of detecting tiny concentrations of specific molecules, may represent a new type of practical and affordable device for various medical applications.
