Book Description
Plasmonic Sensors and their Applications A practically-focused reference and guide on the use of plasmonic sensing as a faster and cheaper alternative to conventional sensing platforms Plasmons, the collective oscillations of electrons occurring at the interface between any two materials, are sensitive to changes in dielectric properties near metal surfaces. Plasmonic sensors enable the real-time study of unique surface properties by monitoring the effect of the material interaction at the sensor surface. Plasmonic sensing techniques offer fast, label-free analysis, and hold advantages over labelling techniques such as ELISA (enzyme-linked immunosorbent assay). Plasmonic Sensors and their Applications examines the development and use of highly sensitive and selective plasmonic sensing platforms in chemistry, biotechnology, and medicine. Contributions by an international panel of experts provide timely and in-depth coverage of both real-world applications and academic research in the dynamic field. The authors describe advances in nanotechnology, polymer chemistry, and biomedicine, explore new and emerging applications of plasmonic sensing, discuss future trends and potential research directions, and more. This authoritative volume: Demonstrates why plasmonic sensing is a profitable method for easy and label-free analysis in real-time Covers a variety of applications of plasmonic sensors, such as disease diagnostics, vitamin detection, and detection of chemical and biological warfare agents Includes a brief introduction to the history and development of plasmonic sensors Provides concise theory and background for every application covered in the text Plasmonic Sensors and their Applications is an invaluable resource for analytical chemists, biochemists, biotechnologists, protein and surface chemists, and advanced students of biotechnology.

Book Description
Zusammenfassung: This book is a compilation of carefully chosen chapters that cover the subjects of nanoscale matter, sensing, and labelling applications. It is aimed primarily at scientists and researchers who are already involved in theme-based research or who are just starting their careers. Despite the diverse nature of the topics covered, which include a range of materials in various forms and uses, the emphasis is primarily on sensing and labelling phenomena. The book begins with materials quantification in nanoscale systems by using an innovative technique like "molecular secondary ion mass spectrometry without calibration standards". Subsequently, the book features an array of materials such as inorganic semiconductor nanoscale particles, carbon dots, rare-earth oxides, polymer nanocomposites, and a few biomaterials, all of which illustrate their functionality and potential for deployment in a wide variety of sensing applications. Although the book delves into the technical aspects of fabrication workouts to some extent, the focus is predominantly on the physical principles, mechanisms, and relevance involved in sensing and labelling applications. The book covers a wide range of topics that leverage the unique properties of nanoscale materials. By carefully selecting appropriate active materials, the authors explore the detection of LPG, hazardous and explosive gases, as well as humidity sensing and hydrogen evolution. It also delves into photo-sensing and persistent photoconductivity by using nanoscale semiconductors, which are used for heavy metal sensing and UV sensing, respectively. The use of metal nanoparticles in various forms is reviewed to address issues related to water contamination, biofilm protection, and food-borne pathogens. The book also discusses surface plasmon resonance, starting with its basic principles and expanding to its relevance in a broader perspective, with a greater focus on applied biosensing. Nanoscale ferrites and magnetic systems are explored with an emphasis on magnetic sensing and actuation. Lastly, the book explores the use of rare-earth-based nanosystems, highlighting persistent luminescence and up/down-converted transitions, which have unprecedented applications in bioimaging and biolabeling. Every effort has been made to strike a balance between the observed phenomena in the emerging areas of sensing applications and suitable theoretical treatments there in.
