A chemical-analysis device integrated with a metallic-nanofinger device for chemical sensing. The chemical-analysis device includes a metallic-nanofinger device, and a platform. The metallic-nanofinger device includes a substrate, and a plurality of nanofingers coupled with the substrate. A nanofinger of the plurality includes a flexible column, and a metallic cap coupled to an apex of the flexible column. At least the nanofinger and a second nanofinger of the plurality of nanofingers are to self-arrange into a close-packed configuration with at least one analyte molecule. A morphology of the metallic cap is to generate a shifted plasmonic-resonance peak associated with amplified luminescence from the analyte molecule. A method for using, and a chemical-analysis apparatus including the chemical-analysis device are also provided.
