The research team is looking for SMEs, big industries R-Y-D institutions and universities to sign a Services Agreement.
Description:
The technology is offered by an Italian research team with expertise in the field of life nanoscience, biomedicine and nanotechnology.

Up to date, the most widespread commercialised infrared spectroscopy instruments (Fourier Transform Infrared spectroscopy, FTIR) allow to identify the composition of polymer mixtures down to the diffraction limit, equal to the wavelength (10 micrometer). Infrared nanospectroscopy with lateral resolution well below the wavelength has been developed in the last years. The offered technology is an innovative infrared nanospectroscopy tool capable to identify the composition of polymer mixtures, co-polymers and composites with feature size down to 50 nanometers. Currently, infrared nanospectroscopy is mostly developed by scattering-type instruments that require an optical detector and work in the non-contact mode of the atomic force microscope.

The offered method instead works in contact-mode (the probe tip touches exactly the point where the chemical composition has to be determined) and does not require any optical detector. In the offered technology, a gold-coated atomic force microscope probe acts as an "infrared nanoantenna" and concentrates the mid-infrared radiation, emitted by a tunable infrared laser (quantum cascade laser), into a nanometric volume. The infrared absorption spectrum of the polymer sample portion contained in that nanometric volume is measured either by scattering detection (optical) or by photoexpansion detection (mechanical). The resolution attained are in the range 50 to 100 nanometers.

The instrument operates like a scanning probe microscope with local infrared spectroscopy capabilities. In addition, infrared nanoscale multi-spectral images of the different polymer species are recorded. The available wavelength tuning range is 5 to 11 micrometers, the laser linewidth is 1 wavenumber. The instrument is commercial and, for its very specific features and the complexity of its functions, its operation requires highly skilled personnel. Through its direct application on Materials, Polymers, Nano - and Microtechnologies, the offered tool can find an useful and effective impact in many fields of activity: Aeronautics -Y- Space, Agrofood, Automotive, Biotech, Healthcare, Environment.

The research team is looking for SMEs/industries, R-Y-D institutions and universities in the field of polymers and polymers composites, or in the above mentioned related ones, to sign a Services Agreement.
Preferred sectors of activity are those involving solid organic materials like plastics, fiber composites, nanostructures. The described technology is offered for services, with partners as end users.

The partner is expected to provide nanostructured samples of materials under development, whose chemical composition and/or nanostructure details are unknown. Expertise in organic chemistry and/or infrared spectroscopy is requested.
The Instrument operation and data interpretation require nano-optics, infrared spectroscopy and scanning probe microscopy capabilities, and are conducted by the client (in the presence of the customer if requested). So, with the use of the tool, the team offers its knowhow and highly specialised expertise in the realization and development of the measurements and related operations.

Advantages and Innovations:
Infrared spectroscopy is the main tool for polymer identification, however it becomes useless when investigating plastic samples with structural features below 1 micrometer, i.e. shorter than the infrared wavelength.
The offered technology is a new infrared nanospectroscopy tool capable of identifying the composition of polymer mixtures, co-polymers and composites with feature size down to 50 nanometers. In addition, through this technology nanoscale multi-spectral images of the polymer samples are also provided.
