Photochemical properties of new bis-cyanine dye as a promising agent for in vivo imaging

Photochemical properties of a new bis-cyanine dye have been investigated, including spectral kinetic characteristics of singlet and triplet excited states as well as affinity to BSA as a representative blood protein. The results obtained reveal, that the dye is a promising agent for imaging and fluorescent labeling of biomacromolecules.
