摘要：

The surface structures of DNA oligomers, pAAAAAAATTTTTTT, deposited on Cu(111) surface have been characterized at liquid nitrogen temperature using a scanning tunneling microscope. Four different types of adsorbed structures have been observed in DNA oligomers; (i) an isolated whole molecule, (ii) a shortened molecule, (iii) a cluster, and (iv) a double helix. The internal structures of the oligomers also have been resolved. (C) 1999 American Vacuum Society. [S0734-211X(99)08104-4].
