This chapter introduces the field of plasmonics, which involves the manipulation of electromagnetic waves at the nanoscale using metal nanostructures. Plasmonics has gained significant attention due to its potential applications in areas such as superlenses, invisible cloaks, and quantum computing. Silver (Ag) is highlighted as a particularly important material in plasmonics due to its ability to support strong surface plasmon polaritons (SPPs) across a wide range of wavelengths from 300 to 1200 nm. The chapter discusses the unique properties of Ag that make it well-suited for plasmonic applications, including its high electrical and thermal conductivity, stability in air, and relatively low cost compared to other metals. The chapter also reviews various methods for synthesizing Ag nanostructures, focusing on chemical reduction techniques such as citrate reduction, silver mirror reaction, polyol process, seed-mediated growth, and light-mediated synthesis. Each method is described in detail, including the reaction mechanisms, advantages, and limitations. For example, the citrate reduction method is popular for generating Ag colloids but tends to produce a variety of sizes and shapes. The polyol process, on the other hand, offers more control over the final morphology of the nanostructures, allowing for the synthesis of cubes, right bipyramids, and pentagonal wires. The chapter emphasizes the importance of controlling the size, shape, and environment of Ag nanostructures to optimize their plasmonic properties. It also discusses the role of capping agents and trace ions in influencing the growth and morphology of the nanostructures. Additionally, the chapter explores the potential applications of Ag nanostructures in plasmonics, including their use in plasmonic antennas, circuits, and sensing technologies. Overall, the chapter provides a comprehensive overview of the synthesis and assembly of Ag nanostructures for plasmonic applications, highlighting the advancements and challenges in the field.This chapter introduces the field of plasmonics, which involves the manipulation of electromagnetic waves at the nanoscale using metal nanostructures.
