We have sttutdied the structure of adsorbed DNA and DNA-u-slated molecules, such as adenosine, adenosine triphosphate disodium (ATP-2Na) and shot single-stranded DNA oligomer (3 to 20 base pairs) adsorbed on Au( 111) substrate by scanning tunneling microscopy (STM). Adenosine and ATP are spontaneously adsorbed on the Au substrate in 1.0 x 10^<-4> motel solution, and are imaged clearly as densely packed clusters. The adenosine clusters have been observed as hydrogen-bonded dimers which tend to dissociate with a change in the pH towards the alkaline condition. The ATP cluster has a spherical shape with a diameter of 15O Å. In the case of DNA oligomers, clear STM images can be observed after pre-rinse treatment or electrochemical treatment. The images of all the DNA oligomers are round with a diameter of 30 to 50 Å. This reveals the aggregated structures of DNA at the Au-solution interface. The manipulation of these DNA oligomers can be achieved by the lateral pushing of the microscope tip.
