Synthesis, Characterization, and Applications of Metal Nanoparticles

The most emerging branch of science during the last decade is nanoscience and nanotechnology. Metallic nanoparticles (NPs) have a great role in many scientific fields such as medicine, physics, mechanics, pharmaceutics, and others. In the last few years, scientists found great potential in metal NPs synthesis and applications and even used different spectroscopic or microscopic characterization methods. This book chapter covers the concept behind metal NPs, the advantages and role of metal NPs in pharmaceutical systems, and will focus on the synthetic methods for the production of different metal NPs by using physical, chemical, and biological approaches; allied characterization techniques including spectroscopic, microscopic, and physiochemical techniques; and the applications in medical technology of metal NPs including applications in drug, protein, peptide, and gene delivery; tissue engineering; enzymology; surface coating; biosensing devices; diagnostics and theranostics; in addition to many other applications, concluding with metal NPs’ future potential.
