We present the spectroscopic nano-imaging of single influenza virus particles in the mid infrared spectral region. The X-31 strain of Influenza A is an enveloped virus, which has a lipid and protein layer that contains the nucleocapsid. Virions are drop cast on silicon substrates for near-field imaging. High-resolution near-field microscopy is used to map the amide and phosphate bands of the envelope proteins on a single virion. We have also investigated the evolution of the virus as a function of time, acid treatment and laser radiation.
