NANO-SIZED MELANIN PARTICLES AND METHOD OF PRODUCING SAME |
摘要 |
The present invention provides nano-sized particles of melanin, and the method for formation of the melanin particles 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, and allow concurrent or consecutive formation of melanin by oxidation curing of the dopamine in air (polymerization). The manufacturing method according to the present invention can produce nano-sized melanin particles in a short period of time. Furthermore, the nano-sized melanin particles made according to the present invention are distinctive from conventional solvents containing dispersions of natural melanin and synthetic melanin, and have excellent application in various fields. |
