This basic phenomenon is used to probe the operation of a DNA-based machine
through the assembly of CdS nanoparticles on Au electrode [

]. The machine
includes a nucleic acid “track,” (1) that binds a primer, (2), through hybridization
to a predefined domain. Figure
5.8
depicts the principles for the DNA-machine-
induced assembly of aggregated CdS nanoparticles on an electrode support. The
synthesis of the DNA occurs on a “DNA track” (1) that consists of two regions I
and II, Fig.

a. Region I is complementary to the primer (2). The sequence II is
