Functional Surface Modifications of Nanostructures

Dear Colleagues,

Nanostructures (comprising nanoparticles, nanoclusters, nanocrystals, nanorods, nanostars, etc.) are currently in the focus of many research groups mainly due to their unique features which are not accessible, nor possible to achieve in bulk materials containing the same chemical elements. The surface of nanostructures is a very important aspect, and particularly in nanoobjects of units of nanometers in diameter, the most dominant part. In general, surface represents an interface between the inner part of nanostructures and surrounding environment. In many cases, the surface dictates the resulting characteristics of nanostructures. It is thus no wonder that many researchers are examining the possibilities and limitations of nanostructure surface modifications. Functional surface modification of nanostructure surfaces can lead to improved properties and, consequently, improved applicability of the nanostructures. Functional surface modification can be performed either in the course of nanostructure formation, i.e., in situ modification, or later on, after nanostructure synthesis, i.e., post-synthetic modification. In fact, even the careful design of the synthetic procedure can be a way to achieve a controlled structure or composition at the nanomaterial surface. The major aim of this Topic is to collect original and innovative reports (original research papers, communications, or reviews) and developments dealing with functional modifications of nanostructure surface(s) leading to improved characteristics of nanostructures, such as better solubility, higher stability, reduced toxicity, enlarged applicability, etc.
