The developed analysis method was applied to various single - molecule junctions, i.e., those of 1,4 - butanediamine (DAB), pyrazine (PY), 4,4» - bipyridine (BPY), and fullerene (C60), sandwiched
by gold electrodes, and the different molecular - dependent electronic and structural fluctuations were demonstrated.

The cylinders will be sandwiched between
electrodes of
gold - plated silicon but also separated from them
by thin spaces of vacuum — the test masses will float on the
electrodes» electrostatic field.
The binding events localize
gold nanoparticles in an
electrode gap; silver deposition facilitated
by these nanoparticles bridges the gap and leads to readily measurable conductivity changes.
To do this, they «chemically assembled a series of double - dot SETs
by anchoring two
gold nanoparticles between the nanogap
electrodes with alkanedithiol molecules to form a self - assembled monolayer,» explained Yutaka Majima, a professor in the Materials and Structures Laboratory at the Tokyo Institute of Technology.
The team began their work
by fabricating the
electrodes of the SET, which were separated
by a nanometer scale gap, with an electroless
gold - plating technique.
Electric current between
gold (Au)
electrodes is modulated
by the deformation imposed
by the wrinkles.
In 2003, however, researchers at the University of Groningen in the Netherlands who mounted single molecules of diarylethene between
gold electrodes found that, even though the switches could be turned off
by visible light, they could not then be turned back on
by ultraviolet.
