Abstract: Two-dimensional graphene offers interesting electronic, thermal, and mechanical properties that are currently being explored for advanced electronics, membranes, and composites. Here we synthesize and explore the biological applications of nano-graphene oxide (NGO), i.e., single-layer graphene oxide sheets down to a few nanometers in lateral width. We develop functionalization chemistry in order to impart solubility and compatibility of NGO in biological environments. We obtain size separated pegylated NGO she… Show more

“…Saturable absorption is observed as a consequence of Pauli blocking 13,14 , non equilibrium carriers result in hot luminescence 15 . Chemical and physical treatments also enable photoluminescence [16][17][18][19] . These properties make it an ideal photonic and optoelectronic material.…”

“…First, such MBs might be easily separated, allowing for operations unique to heterogeneous assays such as washing and signal amplification. In addition, nanomaterials may protect DNA and facilitate DNA delivery into cells, [12][13][14] avoiding the use of transfection agents or microinjection. [15][16][17] Finally, several different probes can be attached to the same particle for multiplexed detection.…”
