Abstract
A test system may be used to measure biological samples and other samples. Samples may be placed on a test substrate such as a test slide or other transparent substrate. The substrate may have patches of reactant-coated gold nanorods or other nanostructures that exhibit plasmonic resonances. An accessory may be removably coupled to a portable electronic device such as a cellular telephone. The accessory may have a lens and a light source that emits light into an edge of the test slide. The light may scatter from the nanostructures in a perpendicular direction towards a camera in the portable electronic device so that the portable electronic device can gather images of the illuminated substrate and measure spectral shifts associated with reactions between the samples and the reactant, thereby helping to analyze the composition of the samples.
