Nanohole array could serve as multifunctional sensing platform

In a study published in Small, researchers created a nanohole array film for sensing applications.

Scientific Achievement

A large-scale framework with built-in vertical nanohole arrays is demonstrated using a unique two-step fabrication method. 

Significance and Impact

This approach creates large-scale surface plasmon nanohole arrays. The strong surface plasmon modes in the nanostructures can serve as reusable optical sensors for trace-amount detection and tracking of biomolecules.

Research Details

  • Fabrication was performed at Purdue University. The nanoholes are 6 nm on average, with a packing distance of 8 nm and high epitaxial quality. 
  • Optical spectroscopy was performed at the Center for Nanoscale Materials (CNM), and numerical simulations were performed using CNM’s Carbon cluster. 

Work was performed in part at CNM.
