ABSTRACT
One-dimensional (1D) and quasi-1D systems, such as nanowires, nanobelts, and nanotubes, have been the focus of intensive research due to their unique physical and chemical properties. The aforementioned applications require Zinc oxide (ZnO) nanostructures in different morphologies, such as nanowires, nanorods, and nanobelts, which must be subjected to postsynthesis procedures to achieve the desired functionality. ZnO nanowires not only possess a large number of surface sites, owing to their nanoscale morphology, but they also provide a favorable microenvironment for retaining the bioactivity of the functionalized enzyme or antigens on the nanowire surface. To effectively engineer the surface of ZnO nanowires for biological sensing, an in-depth understanding of the surface phenomenon and interactions is crucial. The authors synthesizes ZnO nanowires in a customized chemical vapor deposition furnace and established the morphology and composition of the synthesized nanowires through scanning electron microscopy, transmission electron microscopy, and x-ray diffraction.
