Manipulate light on the nanoscale: Proposed quantum dot–graphene scheme improves conversion of light into surface waves

By Lisa McDonald / December 11, 2020

Surface plasmon polaritons are a type of surface wave that, when harnessed, show potential to improve various processes that take place on the nanoscale, such as molecular imaging. Researchers from two places in Russia propose a new scheme using quantum dots and graphene to more efficiently convert light into surface plasmon polaritons for use in such applications.

Identify molecular ‘fingerprints’: Proposed graphene-based nanofocused sensor may improve molecular analysis

By Lisa McDonald / July 24, 2020

Mid-infrared spectroscopy is an important tool for nondestructive analysis of molecules, but it cannot analyze nanometric volumes very well. One way to improve nanometric analysis is through a technique called nanofocusing, and researchers in Spain and Russia proposed an improved nanofocusing technique using graphene.
