Reversible in situ structural transitions

The adsorption of dsDNA onto gold electrode surfaces shown by STM and AFM images obtained by Lindsay et al. [83-86] demonstrates that DNA molecules adsorb on the surface reversibly and can undergo conformation transitions. Additionally, the electrochemical deposition and in situ potential control during imaging can be used to obtain reproducible STM images of the internal structure of adsorbed ssDNA and dsDNA. Spectroscopic techniques... [Pg.396]

Also the reverse transition, the formation of a (1 x 1) structure on the domain network of the (v x y )R30° phase can be followed in-situ by STM. Figure 3 shows the evolution of the surface structure upon a potential step from the (v X v )R30° into the (1x1) Cu UPD phase. Starting from the domain... [Pg.241]
