Query: Surface Engineering of Synthetic Nanopores by Atomic Layer Deposition
  and Their Applications   In the past decade, nanopores have been developed extensively for various
potential applications, and their performance greatly depends on the surface
properties of the nanopores. Atomic layer deposition (ALD) is a new technology
for depositing thin films, which has been rapidly developed from a niche
technology to an established method. ALD films can cover the surface in
confined regions even in nano scale conformally, thus it is proved to be a
powerful tool to modify the surface of the synthetic nanopores and also to
fabricate complex nanopores. This review gives a brief introduction on nanopore
synthesis and ALD fundamental knowledge, then focuses on the various aspects of
synthetic nanopores processing by ALD and their applications, including
single-molecule sensing, nanofluidic devices, nanostructure fabrication and
other applications.
