Figure 6

(a) Left: Qdot705 imaged with STED nanoscopy, i.e., with both the STED and the excitation beam. Right: The same sample imaged only with the doughnut-shaped STED beam. (b) Survival fraction during continuous STED illumination compared for different types of fluorescence probes. (c) Left: Average fluorescence brightness and SNR of Pdot−streptavidin and Qdot−streptavidin. Right: Average fluorescence brightness and SNR of Pdot−IgG and Alexa 488−IgG.
