Intensity fluctuations of individual fluorophores, also termed blinking, are studied at the single‐molecule level by T. Cordes, P. Tinnefeld et al. on p. 931 . Therefore, dye molecules of the homologous series of cyanines were immobilized through double‐stranded DNA on BSA‐coated cover slips. The OFF‐times due to radical‐ion formation increase for larger chromophore size and correlate with redox potentials. Cover artwork by Christoph Hohmann, Nanosystems Initiative Munich (NIM).
