Abstract excerpt

We have investigated peptide nucleic acid (PNA)-mediated aggregation of reduced graphene oxide (rGO) sheets. Addition of PNA into suspension of rGOs resulted in aggregation of rGOs, which could be easily detected with the naked eye. To elucidate the mechanism of rGO aggregation, we monitored the reaction by transmission electron microscopy, zeta potential measurement, and UV-vis spectroscopy. Our findings suggest...
