Abstract

This project aims to develop a multipurpose tool for quantitative nanoscale analysis and manipulation of biomolecular, polymeric and heterogeneous surfaces. Key features of the proposed instrument are 1nm spatial resolution and 1pN force sensitivity; operation in technological relevant environments (air or liquids) and with no impact on the sample surface.

The multifunctionality and flexibility of FT will enable characterisation, control or manipulation of structures on a nanometer-scale, so it will open new approaches for manufacturing at molecular and nanoscale levels. This tool is based on two innovative concepts:

• the bi-modal AFM and
• the multimaterial methodology.

The bi-modal AFM concept considers the cantilever as a three dimensional object with several resonance modes, in particular two. The concept departs radically from the established principles of dynamic force microscopy (only the fundamental mode is considered). The double excitation allows to separate topography from composition contributions in the experimental data. Furthermore, the bi-modal AFM is about two orders of magnitude more sensitive to force variations than state of the art tapping mode AFMs.

The multimaterial methodology will allow to transform the amplitude, frequency or phase shift changes measured by the instrument into quantitative information about the sample properties. The multimaterial methodology has both a general framework to describe dynamic force microscopy interactions and specific codes to be used with different materials such as inorganic materials, biomolecules , polymers or molecular architectures. Specific key goals are:

• topography, composition analysis and manipulation of biomolecules, polymers and heterogeneous surfaces;
• operation in air or liquids environments;
• 1nm spatial resolution and 1pN force sensitivity;
• compatibility with existing atomic force microscopes.
