Video: Silica layer enables tuning of structural colors for biocompatible pigments that don’t fade in tattoos, paints, foods, and more

September 20th, 2017 | by April Gocha, PhD

Researchers report a simple method to manufacture biocompatible structural colors using only melanin and silica. The silica shell provides a buffer layer of tunable thickness that allows customization of the particular color, offering the potential to fabricate a new breed of long-lasting pigments that don’t fade.


Will our sweat someday power our electronic devices?
