Flow fluorescence technology is a clinically applied high-throughput luminescent detection technology based on encoded microspheres and flow technology. It is also known as liquid chip, suspension array, and Luminex? xMAP technology, among others. As a new-generation high-throughput molecular diagnostic technology platform following biochip technology and chemiluminescence technology, it has become a major focus in the field of clinical diagnosis and life science research.

Since the invention of the optical microscope, researchers have been striving to enhance the impact of target signals relative to background noise. Fluorophores have become mainstream signal-generating labels due to their brightness, well-defined excitation and emission profiles, reproducibility, and ease of use in biological systems. However, the use of fluorophores also introduces certain limitations.

In recent years, marine-derived functional foods with anti-tumor effects have attracted increasing attention from researchers. Microalgae, which are rich in proteins, are easy to metabolize and clear in normal cells and have lower toxicity compared with cancer cells; therefore, their anti-cancer effects cannot be ignored. Spirulina platensis is a type of microalgae, and it has a unique green-blue color.
