Abstract: PURPOSE: Nano-sized melanin particles are provided to ensure excellent application in various fields distinctive from conventional solvents containing dispersions of natural melanin and synthetic melanin. CONSTITUTION: Nano-sized particles of melanin comprises the following steps: adding a base to a dopamine H+X - containing solution (where H+X - is an acid) and allowing an acid-base neutralization reaction; and forming nano-sized particles of melanin by controlling the addition of nucleic dopamine H+X - (a) to base (b) at a ratio of a : b = 1 : 0.1 ~ 1. The nano-sized particles of melanin allow concurrent or consecutive formation of melanin by oxidation curing of the dopamine in air (polymerization).
