Carbon dots – fluorescent carbon nanoparticles – can be used for in vivo cell imaging with both one- and two-photon excitation, researchers have discovered. The team, with members from Clemson University, from Peking University in Beijing and from Shanghai University in China, created and identified carbon dots back in 2006, and it has been researching the various applications of the particles ever since. The particles had previously been proved useful as in vitro imaging agents. To test their efficacy as imaging agents, the investigators subcutaneously injected a solution of carbon dots...Read full article
