An optical absorption-induced nanoscale surface expansion was probed to yield the spectral response of silk at IR molecular fingerprinting wavelengths with a high ~20 nm spatial resolution defined by the tip of the probe. Silk microtomed sections of 1-5 micrometers in thickness were prepared for nanoscale spectroscopy and a laser was used to induce amorphisation.
