Analysis of protein-based binding media found in paintings using laser induced fluorescence spectroscopy.
Laser induced fluorescence (LIF) spectroscopy of intrinsic fluorophores from organic media found in paintings (casein, animal glue and egg proteins) provides novel non-invasive means of characterisation of general classes of media on the basis of fluorescence emission arising from the presence of certain amino acids and their degradation byproducts. Proteins from traditionally employed binding media include collagen, casein, albumin and other egg proteins, of animal sources (skins, milk and egg respectively). Wavelength dependence of the spectra is presented for analyses of thin films of protein-based binding media.
