A attempt to harness biological molecules for the direct realization of molecular scale electronics faced with a fundamental dichotomy
- electronic conduction or self-assembly
Any attempt to harness biological molecules for the direct realization of molecular scale electronics faces a fundamental difficulty in that most biological molecules do not conduct electronic currents.
Therefore, it is impossible to realize molecular electronics by biological molecules alone.

The superior electonic properties of these materials are accompanied by very simple chemistry, which does not allow encoding of the large amounts of information needed for the self-assembly of complex constructs.
This author proposed to hybridize between the two material systems
Electronic conduction is provided by metals, semi-conductors,
and conducting polymers.
Self-assembly is provided by DNA molecules and their related
proteins.

The schemes described below consist of two steps.
First, the biological components are utilized to assemble a
template or a scaffold with well-defined molecular addresses.
Second step to localize the electronic devices and interconnect
them electrically.
