Advances in Nanosensors for Biological and Environmental Analysis

Nanoscience and nanotechnology deals with the study and application of structures of at least one dimension of the order of less than 100 nm (1 nm = one millionth of a millimetre). One area of nanotechnology where that has been significant deployment of inspired new products is the development of nanosensors. Nanosensors are tiny sensory devices which monitor the physical or biological or chemical phenomena in regions which are difficult for humans to reach; and then convey the information from there to the external world. They are highly sensitive and thus tremendous research and development is done on them to gather specific and accurate results. This book will present up-to-date information on the various types of biological and environmental nanosensors currently available and then discuss their application fields. Classification of nanosensors is usually determined by the structure of the materials used in their fabrication. For environmental and biomedical applications, these are mainly nanotube or self-assembled materials, which include PNCs such as super-molecular or conducting polymers. Polymer Nanocomposites are a unique class of functional materials used in the development of nanosensors due to their enhanced conductive and biological properties. In order to build this functionality during the design process it is important to have a detailed understanding of molecular interactions at the nanoscale interface. Particular attention will be given in the book to the molecular dynamic of interface reactions. The current state of art in the terms of commercial aspects will also be reviewed. Broadly, the book will provide detailed information on: The emergence of different types of nanomaterials as transduction platforms used in the development of nanosensors. These will include: carbon nanotubes, graphene, 2-D transition metal dichalcogenides, conducting polymers, and metal organic frameworks. The application of biomolecules as biosensing molecular interfaces. These will include examples on antibodies, DNAs, aptamers, bacteriophages, and enzyme-based biointerfaces. There will be extended discussion on different methods of biointerfacing, such as physical adsorption of biomolecules on nanomaterials through hydrophobic interactions and covalent bioconjugation methods. The development of nanosensors in different sensing formats, e.g., electrochemical, fluorescent, and optical fiber. Application of nanosensors for different environmental analytes, such as heavy metals, polluting/toxic gases, bacteria, emerging pollutants, and pesticides. Commercial availability of environmental nanosensors, Cost-benefit analysis, and future research prospects Features detailed information on various types of biological and environmental nanosensors Gives particular attention to the molecular dynamics of interface reactions to build functionality during the design process Includes the current state-of-the-art in terms of commercial aspects
