biomolecular electronics otherwise molecular electronics (rus. электроника, биомолекулярная otherwise молетроника; молекулярная электроника; нанобиоэлектроника) — A cross-disciplinary field of science involving electronics and nanotechnologies where biomolecules and their principles of information processing and energy transmission form the basis for creating elements of electronic devices.


For many decades, molecules and molecular complexes with discrete energy levels and the ability to switch the molecular system from one state to another have been a prototype of the ideal hardware components of computing devices. Compared with the semiconductor element base, molecular components have:

- a higher degree of integration;

- much lower switching energy;

- higher chip stability to ionizing radiation, specifically highly integrated chips.

Molecular electronic components can lead to fundamentally new features, such as:

- complete identity of molecular components, without spread of characteristics due to imminent process errors;

- noise-free single-electron processes;

- specific molecular signal transmission processes that can create logically more complex original elements.

Three-dimensional architecture of molecular sizes should increase computing performance by several orders of magnitude. However, there are technical barriers to overcome, which limit the producibility of such devices.

It is not only computer technology that is interested in the practical application of molecular systems. See the Figure to get some idea of the specific areas of molecular electronics.
