Abstract
In an example implementation, a substance detection device includes a substrate having nanoimprinted chamber walls and nanostructures. The chamber walls define a chamber and the nanostructures are positioned within the chamber to react to a substance introduced into the chamber. A two-dimensional (2D) orifice plate is affixed to the chamber walls and forms a top side of the chamber.
