Cyanine dyes

摘要

Sensitivity and specificity of an optical modality can be enhanced by the use of highly absorbing dyes as contrast agents. Cyanine dyes that absorb and emit light in the near infrared region of the electromagnetic spectrum are disclosed. These dyes are useful for imaging, diagnosis and therapy of various diseased states. Particularly, the molecules of the invention are useful for optical diagnostic imaging and therapy, in endoscopic applications for the detection of tumors and other abnormalities, for localized therapy, for photoacoustic tumor imaging, detection and therapy, and for sonofluorescence tumor imaging, detection and therapy.
