Abstract
Objective: Polydopamine (PDA) is the end product of the auto-oxidation and polymerization process of dopamine monomers. PDA has demonstrated significant potential in biomedical fields, particularly due to its photothermal conversion ability, drug binding capacity, versatile adhesion and bioadhesion capabilities, sensitivity to pH changes, and high biocompatibility. Moreover, its superior features have made PDA-based nanoparticles promising for drug delivery systems and treatments. In this review, a comprehensive evaluation of the potential roles of PDA, polymerization mechanisms, and PDA-based nanosystems in the diagnosis and treatment of various diseases is aimed, with a specific emphasis on highlighting the role of PDA in the medical and pharmaceutical fields.
Results and Discussion: In literature research, PDA-based nanosystems have been recognized as promising systems for diagnosis and treatment in various fields due to their superior properties. Studies on topics such as particle size, stability, drug release optimization, biodistribution and long-term toxicity analysis of PDA nanoparticles are increasing day by day. It is believed that with the clarification of unresolved and understanding of PDA metabolism and biodegradation mechanisms, these systems can effectively contribute to diagnosis and treatment.
