Precision assembly of oppositely and like-charged nanoobjects mediated by charge-induced dipole interactions

Nano Lett. 2010 Jun 9;10(6):2275-80. doi: 10.1021/nl1012079.


The range of electrostatic interactions controls precisely the mutual orientations of assembling charged nanoobjects. For nonspherically symmetric particles, polarization effects and induced dipoles can dominate charge-charge interactions. These charge-induced dipole interactions mediate orientation-specific aggregation of both oppositely and like-charged particles.
