Abstract Surface-enhanced Raman spectra of natural tissue and cancerous tissue of lung from 300 to 1 700 cm-1 were measured. In the cancerous tissue of lung, the orderly conformations of amidesⅢ and amidesⅠof the main chains in protein such as α-helix,β-corner and no rules curly were damaged seriously; conversely, the extendable vibration of skeleton C—N and skeleton C—C increased. Side chains change became complicated. In general, the content of nucleic acids increases in the cancer tissue of lung. The lengthways conformations of lecithoid chains is out-of-order in the cancerous tissue of lung compared with the natural ones.
