S. Sampath Outline

This chapter is organized into sections corresponding to various electrochemical characteristics of nanometallic particles. The introduction gives a brief idea of the basics of colloids together vith related literature. Subsequently, the electrochemistry with nanoparticles and ensembles of nanoelectrodes is explained followed by the electrochemical coulomb staircase behaviour of monolayer-protected nanometallic clusters. The investigation of nanoparticles using techniques based on combinations of different spectroscopic and electrochemical techniques is then reviewed. Sensors and electrocatalysis form the next sections and finally a summary and perspectives are given. 

Electrochemistry has been inherently associated with nanoscience, particularly when the stability and the assembly of the particles are probed using the so-called bottom up chemical approach. The stability of colloids is related to the repulsive forces when the double layers around them overlap with each other. Low electrolyte
