Abstract
Devices and methods for detecting the constituent parts of biological polymers are disclosed. A molecular analysis device comprises a molecule sensor and a molecule guide. The molecule sensor comprises a single electron transistor including a first terminal, a second terminal, and a nanogap or at least one quantum dot positioned between the first terminal and the second terminal. A nitrogenous material disposed on the at least one quantum dot is configured for an interaction with an identifiable configuration of a molecule. The molecule sensor develops an electronic effect responsive to the interaction. The molecule guide is configured for guiding at least a portion of the molecule substantially near the molecule sensor to enable the interaction.
