Summary

The Langmuir–Blodgett (LB) method was inspired on the very concepts of manipulation and control at themolecular level that are so pervasive in what is now referred to as nanoscience and nanotechnology. Originally created to produce organized structures of amphiphilic molecules, the LB technique has been extended to a wide variety ofmolecules – evenmacromolecules – that are assembled in a layer-by-layer fashion, whose properties normally differ considerably from those obtained with the same material in a bulk or thick film. For many years it was believed that industrial applications of LB films would be realized in consumer products, with the inherent advantage of molecular architecture control in thin films. This expectation was not fulfilled for reasons that we shall discuss in this chapter. Instead, the LB method has become a unique tool to investigate molecular-level interactions, being extensively used in proof-of-principle experiments for many applications. In this chapter, after providing a historical background of the LB methodology and describing the experimental procedures for film fabrication and characterization, we concentrate on examples that highlight the uniqueness of LB films. Emphasis will be placed on the use of LB films in studying molecular-recognition processes, in sensing and biosensing, and in signal processing and optical storage.
