ScienceDaily (Apr. 1, 2008) — Researchers from several CNRS-associated laboratories have succeeded in synthesizing porous nanoparticles that are capable of absorbing the energy of two photons in the near infrared spectrum, and then re-emitting radiation used for medical imaging by fluorescence. These two-photon nanoparticles should enable the more precise detection of tumor cells and, in the longer term, better-targeted therapy.
