Researchers Explore Butterfly-Inspired Structural Color for Safer Paints
Researchers at Northeastern University (NU) in Boston, US, are investigating the 'structural color' found in butterflies as a potential alternative to chemical-based pigments in paints and glitters. This scientific endeavor aims to develop safer and more durable coatings by mimicking how microscopic structures on butterfly wings interact with light to produce vibrant hues. Unlike traditional pigments, which can fade and contain harmful chemicals like lead, cobalt, and arsenic, structural colors are derived from the physical arrangement of materials. Dr. Leila Deravi, an associate professor of chemistry and chemical biology at NU, is leading the study, focusing on crystalline pterin compounds from the cabbage white butterfly. Her team believes that by adjusting the size and arrangement of these crystals, they can control the resulting color, offering an environmentally friendly and non-toxic solution for various applications.
