Schematic of the setup for photo-thermal induced resonance (PTIR), which includes an infrared laser source and atomic force microscope (AFM) cantilever with a sharp tip that touches the sample and vibrates in response to the sample's light-induced expansion.
Nanosensors that detect chemicals work by measuring the change in the electrical conductivity of the nanomaterial once an analyte has been detected. Many nanomaterials have a high electrical conductivity, which will reduce upon binding or adsorption of a ...
The DARPA Robotics Challenge was a showcase for how very large, very expensive robots could potentially be useful in disaster recovery and high-risk environments. Humanoids are particularly capable in some very specific situations, but the rest of the time ...
The team’s concept could lead to more broad nanofabrication platforms, and even be used to create complex optical nanostructures for biomedical, computation, MEMS/NEMS, and sensing devices. Discuss this story, and other 3D printing topics, at ...
A new class of flat, ultrathin optical devices on a chip was developed by scientists from the Center for Nanoscale Materials at Argonne National Laboratory and Harvard University. The new design uses a microscopic electromechanical device (MEMS ...
