Fluorescence properties of the bio-QDs in C. utilis WSH02-08. (a) Intracellular mean fluorescence intensity trajectories in different synthesized bio-QDs recorded under lamp illumination using fluorescence microscopy; (b) The derivative of non-linear function of the photoactivation process under different synthesis conditions; (c) Best-fit photobleaching decay time constants for the bi-exponential form of the bio-QDs. All the experiments were conducted under the same conditions.
