    摘要: The invention relates to activatable imaging probes that include a chromophore attachment moiety and a plurality of chromophores, such as near-infrared chromophores, chemically linked to the chromophore attachment moiety so that upon activation of the imaging probe by interaction with a target molecule the optical properties of the plurality of chromophores are altered. The probe optionally includes protective chains or chromophore spacers, or both. Also disclosed are methods of using the imaging probes for in vivo and in vitro optical imaging.

    摘要: Nucleic acid-imaging compositions and methods for noninvasive imaging of a nucleic acid introduced into somatic tissues of an animal or human are disclosed. The noninvasive imaging enables quantitative assessment of the biodistribution of the introduced nucleic acid. The disclosed imaging compounds include a base-binding moiety, a phosphate-binding moiety, and a metal-binding moiety. A chelated metal is non-invasively detected for imaging by radioactivity or magnetic resonance.
