Graphium weiskei butterfly wings and scanning electron microscope (SEM) micrograph of their detailed nanostructure. The conical cuticular nanostructures found on the metalicized surface of the G. weiskei butterfly display ideal properties as substrates for avidin/biotin assaying using SERS (12 × 10 μm) (© 2009 WILEY‐VCH Verlag GmbH & Co.

High magnification photomicrograph of a microcalcification (dark blue concretion) in benign breast tissue that was a target for stereotactic breast needle biopsy. Raman spectra of breast tissue such as those shown were modeled and decision algorithms developed using model‐based parameters that accurately distinguished benign breast lesions from breast cancer.
