To address the intrinsic limitation of magnetic actuation, a team of researchers has developed a way to use microbubbles to provide the specificity needed to power micro-robots for biomedical applications.
Scientists have calculated a model of an optical system in which large losses in waveguides are compensated by a small gain. The newly discovered phenomenon means that a signal can be transmitted with virtually no losses, which up until now had been an unresolved issue with plasmonic and nanooptic devices.
Researchers have improved the design of tiny nanodiscs - synthetic models of cell membranes used to study proteins that control what enters and leaves a cell. The enhancements provide an unprecedented view of how viruses infect cells.
Has the time come to replace traditionally used silicon with printable organic semiconductor inks? Scientists believe so, especially for future electronics that need to be flexible, lightweight, wearable and low-cost.
Researchers have adapted an 'off-the-shelf' hazard assessment tool for use with emerging nanomaterials in an effort to better understand threats they may pose to workers, the public and the environment.
