Phycocyanin, a pigment-protein complex in cyanobacteria and red algae, plays a key role in photosynthesis by capturing and transferring light energy. It offers health benefits such as anti-inflammatory properties and liver support and is widely used as a natural blue pigment in food and cosmetics. Research explores its potential in drug delivery, imaging, and other biomedical applications. Additionally, it serves as a bioindicator for monitoring water quality and cyanobacterial blooms.
