The fluorescence of propidium iodide (PI) can be effectively quenched with the addition of graphene oxide (GO) in aqueous solution, due to the formation of a physical adsorption material named GO–PI. A fluorescence enhancement of approximately 80 times can be observed after addition of a certain amount of DNA/RNA into the above-mentioned solution. Meanwhile, it is found that the GO–PI can enter into the nuclei and stain the DNA/RNA of living human breast cancer cells MCF-7, while PI alone cannot cross the cellular membrane in the control experiment, demonstrating GO can be employed to be an efficient PI delivery nanomaterial for live cell staining.
