Nanobiotechnology. Coordinator: Zuccheri

The nanobiotechnology research group employs nanotechnological techniques and strategies towards the characterization of biological systems (through ultramicroscopy, single-molecule techniques, biosensors) and it exploits the features of biological molecules for designing and making nanosystems.

Research themes

Atomic Force Microscopy: The research group develops nanotechnology techniques, with a focus on Atomic Force Microscopy. These are used to characterize nucleic acids, nucleoprotein complexes, proteins, biological nanostructures and nanostructured materials (surfaces, nanoparticles, nanofibers, nanostructured polymers). Single molecule force spectroscopy is used to study the conformational equilibria in proteins or to characterize the interactions amongst molecules.

DNA nanotechnology: The group exploits Structural DNA Nanotechnology, the strategies to design the self-assembly of DNA nanostructures to make functional nanostructures (for biosensing or other applications).

Biosensors: The groups works at the development of biosensing systems, especially focusing on the recognition of biomolecular analytes from solutions. The group main experience lies in the use of biosensors based on nucleic-acids.

Advanced cell culture: we are working at the development of methods for advanced and 3D cell culture, also in the context of a research project funded by the American Association for Amyotrophic Lateral Sclerosis.

The group can provide technical services in atomic force microscopy and related techniques (with the assistance of optical microscopy) for the characterization of biomolecules, nanostructures and materials, including nanomechanical analysis. Please, contact the coordinator for details.
