Dramatic advances in modem fluorophore technology have been achieved with the introduction of Alexa Fluor dyes by Molecular Probes (Alexa Fluor is a registered trademark of Molecular Probes). Alexa Fluor dyes are available in a broad range of fluorescence excitation and emission wavelength maxima, ranging from the ultraviolet and deep blue to the near-infrared regions. Because of the large... [Pg.137]

Even more elegantly, the local resolution is improved by irradiation with very intense focused femtosecond laser pulses outside the absorption range of the fluoro-phore (e.g., in the near-infrared). The very intense focus of the laser beam—and only this—will excite the fluorophore by nonresonant two-photon absorption. Artifacts by scattered primary radiation are ruled out and the local resolution is comparable to a confocal microscope. In addition, the damage of the sample by laser light absorption is reduced to a minimum. [Pg.232]

Cyanines are by far the most popular and extensively researched chromo-phore for use in biological and medical imaging applications [70,72], They are used almost exclusively in fluorescence-related protocols. Their popularity may be attributable to factors such as their excellent synthetic flexibility and fluorescence properties, the latter being very high in some instances. Cyanines are the only synthetic near-infrared fluorophores which are commercially available (for... [Pg.578]
