Nanoparticles Find And Repair Cracks In Electronics
Microscopic cracks in wires printed on circuit boards can shorten the life of the electronic gadgets that have become indispensable nowadays. But those invisible cracks are hard to find and fix. A simple new repair system based on self-propelling nanoparticles offers hope for circuit healing (Nano Lett. 2015, DOI: 10.1021/acs.nanolett.5b03140). The engineered nanoparticles—made of gold and platinum and suspended in a hydrogen peroxide solution—autonomously detect surface cracks . . .
