Disentangling melanin self-assembly via nanoprecipitation: from protoparticles to supraparticles

Key Points

• The research aims to explore how melanin can be assembled into larger structures using nanoprecipitation.
• Nanoprecipitation technique was utilized to control the aggregation of melanin.
• Melanin nanodiscs were formed and then aggregated into larger particles called supraparticles.
• Examined the size range of resulting supraparticles (30–100 nm).
• Successfully created few-nanometer melanin nanodiscs.
• Aggregated melanin into supraparticles with diameters ranging from 30 to 100 nm.
