Photoacoustic contrast agent-1 perchlorate (Compound F-1) serves as a photo/sono-sensitizer that effectively induces cell mortality under illuminated conditions. This compound is applied in the field of tumor diagnostics and treatment research. Additionally, it acts as a multifunctional dye, which is crucial in various biological experiments. These dyes facilitate the observation and analysis of cell structures, tracking of biomolecules, evaluation of cell functions, differentiation of cell types, detection of biomolecules, investigation of tissue pathology, and monitoring of microorganisms. Their uses extend beyond basic scientific research to include a broad spectrum of clinical diagnostics. Moreover, dyes play a significant role in conventional areas like textile dyeing and in newer sectors such as functional textile processing, food pigments, and dye-sensitized solar cells.
