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 (DNA^T) 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 DNA^T are studied merging experimental and theoretical results. The inverter is designed, and the transient responses are studied.
