Organic molecules exhibit electronic properties that can be uniquely utilized in new generation of electronic nanodevices. Complex three-dimensional information processing, computing and memory architectures can be designed and fabricated using self-assembled biomolecules (DNA and proteins) utilized as functional multi-terminal interconnected electronic nanobiodevices. We examine DNA-based transistors (DNAT) for logic circuits applications. It is important to design and analyze functional high-performance electronic nanobiodevices comprehending basic phenomena and effects in biomolecules–connect complexes. We concentrate our attention on the proof-of-concept device enhancing the maturity of nanobioelectronics and demonstrating its feasibility. Electronic behavior and I–V characteristics of DNAT are studied merging experimental and theoretical results. The inverter is designed, and the transient responses are studied.
