Fig. 1. (IMAGE) Osaka University Caption In the normal sequence (above), electron moves slowly and blinks slowly. In the case of a mutation, electron moves fast and blinks fast. The speed of electron movement is measured in single molecules by the rate of blinking to diagnose point mutations. Credit 2022, Shunya Fan et al.
