    Noble-Metal-Based Composites for High-Performance SPR Sensors
    (Springer, Singapore, 2025) Archana Yadav, M. A. Ibrar Jahan, Sarita Kumari, R. Srujana, Boris A. Malomed, Shatrughna Kumar
    Surface plasmon resonance (SPR) is a very captivating sensing technology because it can find molecules without labels and analyze their interactions in real time. This chapter explores the fundamental principles of SPR, its components, and its applications in various fields. This chapter also explores the noble metal-based composites, particularly incorporation of Gold and Silver have attracted extensive attention of scientific research due to its exceptional abilities to improve the performance parameter of surface plasmon resonance (SPR) sensor. These noble materials possess unique photoelectric properties, good stability and low biotoxicity, which makes SPR sensors highly sensitive and selective detection for the various applications such as biosensing, chemical sensing, environmental sensing etc. Various noble metals, such as gold, silver, platinum, and palladium, are discussed, highlighting their unique optical and electrical properties, stability, and biocompatibility. Furthermore, the chapter explores using composite materials to further enhance the sensing parameters. During the process, different problems are discussed, such as fabrication challenges and cost efficiency. Future issues are also discussed, such as how to combine artificial intelligence (AI) and the internet of things to make advanced sensing possible. The chapter ends with a discussion of how SPR sensing could be used for personalized medicine, smart agriculture, and security purposes. This highlights the need for people from different fields to work together to get around current problems and encourage new ideas.
