Nanoparticles offer hope for common skin allergy
Tiny particles only billionths of a meter in diameter—about two thousand would fit across the width of a human hair—could offer big hope in a small package to the many millions of people who are allergic to the nickel in everything from jewelry to coins and cell phones, say scientists at Brigham and Women's Hospital (BWH).
