Reflectance and corresponding fluorescence microscopy images of triplexed, sealed chamber assay for HIV, SARS, and HCV target sequences. In this assay, only HIV and SARS targets were added. Thus, while all three nanowire patterns are visible in the reflectance image, only the HIV- and SARS-specific nanowires should be visible in the fluorescence image. Nanowire patterns and corresponding probe specificities are given below the images.
