1.1 Introduction

In 1919, Katharine Blodgett and Irving Langmuir, working in the General Electric Research Laboratory in Schenectady, New York, showed that monomolecular films of such insoluble substances as long-chain fatty acids floating on water could be transferred to solid substrates (e.g., glass or metal plates) by a simple dipping procedure.1 Some 15 years later, Blodgett announced the discovery that monolayer transfers could be accomplished sequentially to ...
