• third most prevalent type of cancer in the world. R-phycoerythrin (R-PE) is a phycobiliprotein isolated from red algae such as Solieria filiformis, with fluorescent properties, photodynamic activity and potential for cancer treatment. However, 5-FU toxicity promotes several side effects and R-PE low

• , the HSPC 50 formulation containing R-PE and 5-FU, functionalized with cetuximab, is a promising alternative for the development of co-encapsulation delivery systems as a phototheranostic nanocarriers.

• for more effective, safer, and personalized theranostic treatment of colorectal cancer [11]. R-phycoerythrin (R-PE) is a phycobiliprotein isolated from red algae Solieria filiformis, which is cultivated on the Brazilian coast [12]. Several pre-clinical studies have shown that this protein has
