Figure 4

First-derivative weight percent versus temperature plots for (GT)₁₅ DNA functionalized- (a) SWCNTs, (b) MWCNTs, (c) RGO, and (d) C₆₀. (e) Bar graph to compare the increase in the thermal decomposition temperature of the carbon nanomaterials functionalized with DNA to that of raw/purified nanomaterials. TGA was repeated three times (n = 3) for each sample. Two-sample t-tests were performed (**P < 0.01, ***P < 0.001).
