Résumé
Bilirubin has good anti-inflammatory， antioxidant and immunomodulatory effects， but its poor water solubility and low bioavailability greatly limit its clinical application. Researchers have developed bilirubin into various nanoparticles， which effectively eliminate the limitation of low solubility of bilirubin with the advantage of dosage form， so that they can maximize its pharmacological activities such as anti-inflammatory， anti-oxidation and immune regulation. Bilirubin nanoparticles have great application potential in a variety of gastrointestinal diseases， liver and kidney diseases， skin diseases， autoimmune diseases， islet transplantation and targeted therapy of tumors （both as a direct anti-tumor drug and as a drug delivery system）. The study of bilirubin nanoparticles will promote the clinical application of bilirubin and the development of related new drugs.
