Scientists observe composite superstructure growth from nanocrystals in real time

For the first time, scientists and engineers have observed in real time how two types of nanoparticles made from different materials combine into new composite materials. The findings, reported by a team led by the University of Pennsylvania and University of Michigan, could help engineers have more control over the assembly of materials that combine the desirable properties of each particle—such as photoluminescence, magnetism and the ability to conduct electricity.
