Nanostructured sensing systems, selectivity

In this report we shall focus on some few, subjectively selected examples of nanostructures that are finite in either two dimensions (i.e., chains) or in three dimensions (i.e., clusters or colloids) and not discuss those that are finite in one dimension (surfaces). The choice is made of two reasons. At first it matches the scientific interests of the author and, secondly, it makes it possible to keep the presentation at an acceptable size. But even with this restriction, it is absolutely impossible to discuss just a fair part of all the recent theoretical studies of such systems. Therefore, we have ehosen to present some few studies in some further details thereby, hopefully, providing a description of the current state of theoretical research in the properties of such nanostructures. We emphasize that the studies that we are going to discuss not are supposed to be better in any sense than those we are not discussing, but rather are considered as being typical. 

A new electrochemical detection strategy based on the adsorption behavior of nanostructured materials toward HMIs has been introduced to enhance the selectivity and sensitivity of electrochemical sensing platform. Various nanostructured materials including nanoscaled carbon, nanostructured metal oxides, micro/nanoporous ion-imprinted polymer, etc. have been explored for their use as electrode modifiers. We believe that the evolvement of adsorption behaviour-intrigued nanostructured materials-based electrochemical systems will lead to the development of novel HMIs detection tools with interest for applications in field such as environmental monitoring and other safety and security controls. The concept is also helpful to...
