Surface Enhanced Raman Spectroscopy (SERS) has emerged as a robust analytical tool for the analysis of single-molecule level sensitivity and its capacity of quantitative detection. This comprehensive book focuses on SERS-based techniques for the detection of infectious diseases. The book discusses the applications of SERS labels and tags, the importance of nanomaterials for the fabrication of SERS substrates/nanotags in the biomedical domain, and the fabrication of robust portable devices with enhanced features. The advantages of SERS integration are compared with traditional detection methods and point-of-care methods, and the integration of SERS-based techniques with smart digital technologies is discussed. This book provides a broad perspective for researchers, academics, clinicians, and readers to use nanotechnology and other methodologies with SERS-based techniques for potential advanced diagnostics of emerging infectious diseases.Key Features Focuses on the advances in SERS technology as a highly important diagnostic technique Covers the elements of fabrication of SERS tags/labels for better enhancement factors Includes applications of SERS in the detection of various infectious diseases Incorporates the development of SERS-based technology combined with other diagnostic approaches to facilitate the next generation of diagnosis of infectious diseases Contains chapters written by world-class researchers in the field Highlights point-of-care applications with SERS
