WebIt belongs to the family of cyanine dyes, which are characterized by their strong absorbance and emission in the near-infrared (NIR) range of the electromagnetic spectrum. This feature makes Cyanine5.5 Dye particularly useful in imaging applications as NIR light can penetrate deeper into tissues compared to visible light. WebCyanine dyes play an indispensable role in contemporary chemistry and biology. The characteristic feature of cyanines is an odd-numbered polyene linker connecting two nitrogen-containing heterocycles, which is responsible for their photophysical properties and unique chemical reactivities.
