Single-walled carbon nanotubes as near infrared fluorescent sensors : characterization, biological and analytical applications

[摘要] (cont.) The total uptake of both SWNT and Au nanoparticles is maximal at a common radius of 25 nm when scaled using an effective capture dimension for membrane diffusion. The ability to understand and predict the cellular uptake of nanoparticles quantitatively should find utility in designing nanosystems with controlled toxicity, efficacy and functionality. The development of such single molecule detection technologies for ROS motivates their application to many other unexplored signaling pathways both in vitro and in vivo.
