Chemical Modification of Si Nanowires for Bioconjugation

摘要

One-dimensional nanomaterials,such as nanotubes and nanowires,have been investigated in detail for numerous applications due to their extraordinary optical,mechanical,and electrical properties.In the context of both processing and properties of nanowires (NWs),a detailed understanding of their surface chemistry is required to meet the technological applications of NWs.For example,the chemical and electronic stability of the surface of NWs is particularly important for applications including nanowire-based logic elements and chemical and biological sensors,which require direct interfacing with their surrounding environment.While there have been many efforts to chemical modifications of carbon nanotubes,there have been a few reports on chemical modifications of NWs.
