Figure 2From: CdSe/ZnS Quantum Dots trigger DNA repair and antioxidant enzyme systems in Medicago sativacells in suspension cultureHistogram of comet distribution. A) Histogram of comet distribution for cell suspension cultures added with 0, 10, 50 and 100 nM of MPA-CdSe/ZnS QD and subjected to 50°C during 20 min based on the comet score with the A/N version. B) Images of comets that represent the 0–4 classes for visual scoring.Back to article page
