title: Nanostructuring of heme-proteins for biodevice applications.
abstract: Proteins represent versatile building blocks for the realisation of nanostructured materials to be applied in the nanobiotechnological field. The Langmuir-Blodgett (LB) technique was utilised as a means to develop nanobiodevices based on protein molecules. Namely, engineered Cytochrome P450 thin films were fabricated and characterised. The possibility to employ LB-based protein structures to use in biosensors has been exploited. The characterisation process was performed in order to verify the best working parameters. As a first step' the protein films were studied at the air-water interface and then transferred into a solid support for further characterisation. The films were characterised by different techniques such as: UV-vis spectroscopy, nanogravimetry, atomic force microscopy and biochemical assays. The results showed that it was possible to form active cytochrome P450s nanostructures by the LB technique.
