Combinations of several enzymes in a production chain are preferred to “first generation” enzymatic processes (where the "single reaction - single enzyme" principle was followed), for the synthesis of compounds with high added value starting from simple and cheap substrates. An important requirement for obtaining control in "cascade enzymatic reactions" is the ability to deliver from one biocatalyst to the next one the various intermediates, limiting as much as possible the diffusion of the latter in the solvent.

Quartz tuning forks are employed in scanning atomic force microscopy (AFM), as well as in some derived techniques, as high sensitivity detectors of interactions, of both conservative and dissipative kind, between the AFM nanometric probe and the investigated surface. However, the contributions of the two kinds of interaction result as convoluted in the sensor response, preventing fully quantitative measurements of the quantities of interest.

The environment as well as the food production provide a number of both natural and synthetic compounds whose effects on human being as an organism have not yet been determined nor investigated.

The proposed technology deals with the development of active SERS (Surface Enhanced Raman Scattering) substrates ad hoc designed for diagnostics of cultural heritage. The substrates are prepared starting from common commercial 'polishing film' sheets (lapping optical fibers) showing an intrinsic roughness (48- 1000 nm) that favors the SERS effect. A pattern of silver or gold nanoparticles are deposited on these films through Pulsed Laser Deposition (PLD).

The instrument which is under development is a non-conventional portable Raman spectrometer. Raman spectrometers provide the molecular composition of the material surfaces, essential for their identification. The instrument peculiarity relies in the simultaneous acquisition of Raman spectra at imaged position and at different micrometric distances (offset) from the laser illumination area.

Recently, it has been demonstrated that Raman spectroscopy can play a fundamental role in assisting the work of the anatomopathologist by allowing classification of oncological samples with practically 100% accuracy in oncological diagnosis.

The development of an innovative screening platform of natural marine extracts guided by biological assays represents one of the main products developed within the Antitumor Drugs and Vaccines from the SEA (ADViSE) project which aims to provide a new vision in Drug Discovery processes.

The study of proteins is typically limited to notions, sometimes with the aid of virtual 3D models, obtained from visualization programs. A knowledge of this type, although useful, limits the ability to acquire a more direct knowledge, almost never leads to awareness of dimensions, and is particularly difficult for those who do not have a strong capacity for three-dimensional imagination.

Electrochromism is an optoelectronic characteristic of particular interest because it can be exploited in the creation of technologies such as smart windows (Smart Windows) to promote energy efficiency, automotive, sensor or visualization devices. Electrochromic materials change their optoelectronic characteristics, showing different colors depending on the applied electric field.

EXPO is a software for the determination of the atomic structure of various materials (organic, metallorganic, inorganic), available in the form of microcrystalline powders, in order to derive the structure-property relationships. EXPO requires the molecular formula of the material, the experimental X-ray diffraction data and, in some cases, the expected molecular geometry.

QUALX is a software for qualitative and semi-quantitative phase analysis of materials (organic, metallorganic, inorganic), available in the form of microcrystalline powders. It uses a database distributed together with the software. QUALX identifies the crystalline chemical phase, one or more of than one, present in a material and determines approximately the weight percentages of each phase present in a mixture.

The substitution of fossil derived monomers in thermosetting resins is a very important point to look at to face environmental impact issues related with the use of traditional resins. The research group set up a protocol for the preparation of thermosetting resins starting from vegetable oils with different composition to substitute the petroleum-based monomers. The materials obtained in this way have a bio-based carbon content higher than 80%.

Our team can develop low-cost ultra-flexible sensors integrated on plastic substrate for volatile organic compounds (VOCs) and gas detection. These devices combine scalable fabrication technologies, implementing active materials such as nanostructured metal oxides or stack of nanostructures decorated with metal nanoparticles, thus enabling a high sensitivity (in the range of hundreds of ppb). These devices can be applied to numerous industrial and commercial sectors and they can be embedded in systems that are more sophisticated.

uManager is a management game designed to foster the development of young students' entrepreneurial skills and abilities. The game offers the opportunity to manage a tourist village, stimulating the skills of decision making and problem-solving in a simulated scenario adhering to the real one. uManager is suitable for use in the classroom or at a distance, in formal and informal contexts.

VOLIS is an online platform that contains various tests for assessing Italian Sign Language (LIS) comprehension skills in signing children, from 4 to 11 years of age. The consequences of some difficulties such as deafness, cognitive impairments and autism spectrum disorder may affect learning, social interaction and broad communicative skills. The use of LIS may support children that have difficulties in acquiring and using a using spoken languages.
