Silver dendrites, a special morphological nanostructures of silver, have received immense attention in nanomaterials field because of their fascinating hierarchical structures and unique properties. Almost a hundred of papers already published regards to this fascinating nanostructures. Depending on the techniques of synthesis, Ag dendrites can be implemented in numerous fields. This book introduces a variety of Ag dendrites preparation techniques, as well as their preparation parameters. The involved growth mechanisms are investigated in order to control the formation progress more effectively. With regard to the applications, this book mainly discusses on surface enhanced Raman spectroscopy, catalysis, superhydrophobic surface, photodetection and surface enhanced fluorescence by using Ag dendrites.
