The application of GO derivatives to amplify clinic samples.

Notes: The template is mitochondrial DNA from human blood genomic DNA obtained from clinic samples. M: DNA marker; 1: first-round PCR; 2: second-round PCR; 3: third-round PCR; C: control experiments without GO derivatives. The concentrations of GO-PAA, GO-PAM, GO-PEG and GO-pSB are 0.6 μg mL⁻¹, 2.4 μg mL⁻¹, 4.8 μg mL⁻¹ and 19.2 μg mL⁻¹, respectively.

Abbreviations: GO, graphene oxide; PAA, polyacrylic acid; PAM, polyacrylamide; PCR, polymerase chain reaction; PEG, polyethylene glycol; pSB, poly(sulfobetaine).
