Layer-by-layer deposition of all-nanoparticle multilayers in confined geometries
Nanofluidic arrays containing high-aspect-ratio nanochannels were used as a platform for
the deposition of all nanoparticle multilayers. LbL assembly of 6 nm titania and 15 nm silica
nanoparticles resulted in conformal multilayers of uniform thickness throughout the
nanochannels. These multilayers are inherently nanoporous with void volume fractions of
about 0.5. Compared to unconfined assembly of the same materials on flat substrates,
thinner multilayer films were observed for the case of deposition within confined channel …
