| Lego-like modular components make building 3-D 'labs-on-a-chip' a snap Posted: 22 Sep 2014 12:28 PM PDT Thanks to new Lego-like components, it is now possible to build a 3-D microfluidic system (or 'lab-on-a-chip') quickly and cheaply by simply snapping together small modules by hand. |
| Engineers unlock potential for faster computing Posted: 22 Sep 2014 12:28 PM PDT Engineers discovered a way to create a special material -- a metal layer on top of a silicon semiconductor -- that could lead to cost-effective, superfast computers that perform lightning-fast calculations but don't overheat. This new "topological insulator" behaves like an insulator on the inside but conducts electricity on the outside. |
| New chip promising for tumor-targeting research Posted: 22 Sep 2014 11:58 AM PDT Researchers have developed a chip capable of simulating a tumor's 'microenvironment' and plan to use the new system to test the effectiveness of nanoparticles and drugs that target cancer. The new system, called a tumor-microenvironment-on-chip (T-MOC) device, will allow researchers to study the complex environment surrounding tumors and the barriers that prevent the targeted delivery of therapeutic agents. |
| Posted: 22 Sep 2014 10:07 AM PDT Electrical engineering researchers have developed a unique nanoscale device that for the first time demonstrates mechanical transportation of light. The discovery could have major implications for creating faster and more efficient optical devices for computation and communication. |
| Graphene imperfections key to creating hypersensitive 'electronic nose' Posted: 22 Sep 2014 10:05 AM PDT Researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times. |
