Inorganic Nanocrystals and Surfaces: An Overview

This chapter presents a general introduction to the main subject of the book: the surface chemistry of colloidal nanocrystals. It starts with a brief historical perspective and then describes the context in which some discoveries have occurred, concerning the synthesis and surface modification of colloidal nanoparticles. In addition to this thematic retrospective, the chapter is intended to highlight current research topics and also to put into perspective future developments. The remainder of this introductory chapter is dedicated to fundamental concepts usually found as core themes of distinct scientific specialties, which can easily be found elsewhere but are usually spread throughout different literature sources and in distinct contexts. Solid surface energetics and structure, the nature of the solid/liquid interface in colloids, adsorption mechanisms, the chemical design of surfaces and the stabilization and assembly of colloidal nanoparticles are among the topics that are concisely approached here. Although this approach is admittedly incomplete taking into consideration the complexity of the topics, it is hoped that this introduction will also provide a platform of basic knowledge for studying the surface chemistry of nanocrystals as elaborated upon in subsequent chapters.
