Figure 4From: Effects of long-term exposure of gelatinated and non-gelatinated cadmium telluride quantum dots on differentiated PC12 cellsProliferation assay. Graph of MTT assay after 10 and 16 days showing the rate of proliferation of differentiated PC12 cells after exposure to concentrations [10-9 M] of the gel and non-gel QDs. Positive control shows differentiated PC12 cells without exposure to QDs; the graph also shows differentiated PC12 cells which were exposed with red and orange QDs of gel and non-gel types after neurites were grown for 10 days. Symbols * and ¤ denote examples of statistical significance in comparison with positive controls using a one-way ANOVA (P < 0.05) by Tukey's mean comparison.Back to article page
