Abstract
We demonstrate that scattering near-field microscopy (s-SNOM) can determine infrared ``fingerprint'' spectra of individual poly( methyl methacrylate) nanobeads and viruses as small as 18 nm. Amplitude and phase spectra are found surprisingly strong, even at a probed volume of only 10(-20) l, and robust in regard to particle size and substrate. This makes infrared spectroscopic s-SNOM a versatile tool for chemical and-in the case of protein-secondary-structure identification.
