Abstract
Directed evolution is a powerful approach to tailor protein properties toward new or enhanced functions. Herein, we use directed evolution to engineer the optoelectronic properties of DNA-wrapped single-walled carbon nanotube sensors through DNA mutation. This approach leads to an improvement in the fluorescence intensity of 56% following two evolution cycles.
