Light enhancement in nanoscale structures could aid cancer detection

Posted by in categories: biotech/medical, nanotechnology

A cutting-edge practice by two Vanderbilt researchers that enhances light in nanoscale structures could help in the detection of diseases like cancer.

The work by Justus Ndukaife, assistant professor of electrical engineering, and Sen Yang, a recent Ph.D. graduate from Ndukaife’s lab in Interdisciplinary Materials Science under Ndukaife, was published in Light: Science & Applications.

In their paper, they show how an engineered nanostructured surface—quasi-BIC dielectric metasurface—can be used to trap micro and sub-micron particles within seconds, which they say helps in the transport of analytes to biosensing surfaces. The metasurface can also serve as a sensor to detect the aggregated particles or molecules, and can be used to enhance fluorescence or Raman signals from the , thereby boosting detection sensitivity, according to the researchers.
