Book Description
Due to their small dimensions, nanoelectrodes exhibit performance enhancements over macrosized electrodes such as: the rapid attainment of steady-state, ability to detect analytes on small time scales, decreased background currents, and high sensitivity. Applications of nanoelectrodes are many and range from the determination of rapid electron transfer kinetics to the in vivo detection of biologically significant compounds such as neurotransmitters. Nanoelectrode ensembles (NEEs) exhibit the enhanced performance characteristics of individual nanoelectodes but have the advantage of packaging thousands of sensors onto a single substrate that is easier to manipulate and yields larger signals than a single nanostructure as a result of thousands of electrodes operating in parallel.

Book Description
Nanotechnology has become one of the most important fields in science. Nanoparticles exhibit unique chemical, physical and electronic properties that are different from those of bulk materials, due to their small size and better architecture. Nanoparticles can be used to construct novel sensing devices; in particular electrochemical sensors. Electrochemical detection is highly attractive for the monitoring of glucose, cancer cells, cholesterol and infectious diseases. Unique nanocomposite-based films proposed in this book open new doors to the design and fabrication of high-performance electrochemical sensors.

Book Description
An electroless deposition procedure for filling the pores in nanoporous filtration membranes with metal (gold) nanowires is described. This method allows us to routinely prepare ensembles of gold nanodisk electrodes in which the nanodisks have diameters as small as 10 nm. Results of electrochemical experiments at ensembles of 30 nm-diameter and 10 nm-diameter gold-disk electrodes are described. The electrochemical response characteristics of these nanoelectrode ensembles are in agreement with predictions of the relevant electrochemical theories. Cyclic voltammetric detection limits for electroactive species at ensembles containing 10 nm-diameter gold disks can be as much as 3 orders of magnitude lower than at a large-diameter gold-disk electrode.

Book Description
Functionalized Nanomaterial-Based Electrochemical Sensors: Principles, Fabrication Methods, and Applications provides a comprehensive overview of materials, functionalized interfaces, fabrication strategies and application areas. Special attention is given to the remaining challenges and opportunities for commercial realization of functionalized nanomaterial-based electrochemical sensors. An assortment of nanomaterials has been investigated for their incorporation into electrochemical sensors. For example, carbon- based nanomaterials (carbon nanotube, graphene and carbon fiber), noble metals (Au, Ag and Pt), polymers (nafion, polypyrrole) and non-noble metal oxides (Fe2O3, NiO, and Co3O4). The most relevant materials are discussed in the book with an emphasis on their evaluation of their realization in commercial applications. Application areas touched on include the environment, food and medicine industries. Health, safety and regulation considerations are touched on, along with economic and commercialization trends. Introduces the principles of nanomaterials for electrochemical sensing applications Reviews the most relevant fabrication strategies for functionalized nanomaterial-based electrochemical sensing platforms Discusses considerations for the commercial realization of functionalized nanomaterial-based electrochemical sensors in the environment, food and point-of-care applications

Book Description
Nanoscale Electrochemistry focuses on challenges and advances in electrochemical nanoscience at solid–liquid interfaces, highlighting the most prominent developments of the last decade. Nanotechnology has had a tremendous effect on the multidisciplinary field of electrochemistry, yielding new fundamental insights that have broadened our understanding of interfacial processes and stimulating new and diverse applications. The book begins with a tutorial chapter to introduce the principles of nanoscale electrochemical systems and emphasize their unique behavior compared with their macro/microscopic counterparts. Building on this, the following three chapters present analytical applications, such as sensing and electrochemical imaging, that are familiar to the traditional electrochemist but whose extension to the nanoscale is nontrivial and reveals new chemical information. The subsequent three chapters present exciting new electrochemical methodologies that are specific to the nanoscale, including "single entity"-based methods and surface-enhanced electrochemical spectroscopy. These techniques, now sufficiently mature for exposition, have paved the way for major developments in our understanding of solid–liquid interfaces and continue to push electrochemical analysis toward atomic-length scales. The final three chapters address the rich overlap between electrochemistry and nanomaterials science, highlighting notable applications in energy conversion and storage. This is an important reference for both academic and industrial researchers who are seeking to learn more about how nanoscale electrochemistry has developed in recent years. Outlines the major applications of nanoscale electrochemistry in energy storage, spectroscopy and biology Summarizes the major principles of nanoscale electrochemical systems, exploring how they differ from similar system types Discusses the major challenges of electrochemical analysis at the nanoscale
