X-ray microscopy is used to observe a specimen by labelling the specimen with a molecule having a double bond, such as, for example, N-succinimidyl-4-nitrophenyl acetate or 5-(dimethylamino phenyl)-2,4-pentadienal, which bond to an amino group, and O-(4-nitrobenzyl)-N,N-diisopropyl isourea, which chemically bonds to a carbonyl group. Such labelling groups can generate fluorescence to facilitate the observation of the specimen. Observation is improved by using a monochromatic X-ray source having a photon energy lower than 2000 eV and a band width narrower than 1 eV.
