The advent of techniques based upon the spontaneous assembly of different materials with control over molecular architecture has afforded the fabrication of composite thin films for many nanotechnological applications. This is the case of the Layer-by-layer technique in which materials bearing opposite charges are assembled via electrostatic interactions on solid substrates. This project is aimed at immobilizing biomolecules such as enzymes and nuclear receptors. A detailed investigation of the adsorption process, including kinetics studies, will be carried out. The structural and morphological aspects of the films will be investigated via spectroscopic and microscopic experiments. Parameters such as biological activity and lifetime will be investigated, aiming at the application of the films as biosensors.
