Novel Approach to Polydopamine Synthesis by Utilizing Nanomaterials

This study explores the influence of different dots on dopamine polymerization. Polydopamine(PDA) nanoparticles were synthesized in the presence of different quantum dots using a buffersolution. The results showed a significant increase in dopamine nanoparticle size from ۵۰ nm to۲۷۹nm and ۳۰۷nm in the presence of dots with different functionalities. The uniform zeta potentialacross samples indicated a consistent surface charge, suggesting the formation of a shell-like PDAstructure around the quantum dots. We attributed the increased nanoparticle size to the role of dotsas nucleation sites for nanoparticle growth and the disruption of the spherical structure by nitrogenatoms in quantom dots. These findings contribute to the understanding of polydopamine layerformation at the nanoscale and may have implications for the development of advanced materials forvarious applications, such as drug delivery, biosensing, and energy storage.
