Heptamethine_dyes
Heptamethine dyes are a subclass of chemical compounds within the cyanine dye family and have many uses as fluorescent dyes, particularly in biomedical imaging, the development of theranostics, the individualized treatment of cancerous patients with the aid of PDT, co-administration with other drugs, and irradiation.[1][2]
The characteristics of heptamethine dyes can be understood by comparing research data on different dyes within the family. For example, the IR-780 dye exhibits a peak spectral absorption of around 780 nm.[3]
