Modification of Glass Surfaces by Phosphorus Dendrimer Layers for Biosensors

Dendrimers [1-3] are well-defined hyperbranched nanostructures emanating radially from a central core. Their perfect structure is due to their method of synthesis. Indeed, dendrimers are never synthesized by polymerization reactions but step by step. In most cases, the synthesis proceeds via a divergent process, that is, from the core toward the terminal functions. Each time the number of terminal functions increases, a new generation is created. These concepts are illustrated in Fig. 6.1.
