Summary:Optical readers are disclosed in examples herein. An example optical reader including a light source to emit a light beam; and a spot pattern generator to receive the light beam and to generate a two-dimensional spot array from the light beam, the two-dimensional spot array to be directed toward a substrate having nanostructures, the two-dimensional spot array to be sensed to detect a presence or an absence of a substance of interest on the substrate.
