Abstract:
Lightening organelles: A femtosecond laser can excite multiphoton-induced luminescence of graphene oxide nanoparticles. The flow, distributions, and clearance of intravenously injected GO-PEG nanoparticles in the blood vessel of mice could be observed clearly by two-photon imaging. The 3D distribution of microinjected GO-PEG nanoparticles in a mice brain could also be reconstructed with two-photon microscopy.
