19_12/2009Fluorescent Nanoprobes: Fluorescent Gold Nanoprobe Sensitive to Intracellular Reactive Oxygen Species (Adv. Funct. Mater. 12/2009)

On page 1884, H. Lee and co-workers report fluorescent gold nanoprobes sensitive to reactive oxygen species (ROS). Using nanoparticle surface energy transfer between gold nanoparticles and end-dopamine modified fluorescein-hyaluronic acid conjugates, gold nanoprobes are created with extreme sensitivity to intracellular ROS. The cover image shows real time monitoring of intracellular ROS generation within macrophage cells via fluorescence recovery of the nanoprobes.
