Silicon nanowires (SiNWs) are 1D structures with diameter ranging from few tens to hundreds of nanometers and length varying from few tens of nanometers to millimiters. SiNWs are fabricated in the labs of the IMM-CNR, Rome Unit, by using bottom-up technologies such as plasma enhanced chemical vapor deposition (PECVD) at low growth temperature ((≤350°C), allowing the use of plastic and glassy substrates. Their electrical properties can be tuned by controlling the p/n doping during the growth.

We propose an optical technique for the fast check of the presence, on the exposed surfaces of persons and objects, of explosives and their precursors, or drugs, or in general materials which are not allowed in restricted environments: airports, courts, places of worship, etc. The technique yields bi-dimensional pictures, with exposure time of < 1 sec, reporting the target substances, and their locations and quantities. The technique already provided laboratory preliminary results, to be completed, and fully validated for sensitivity and selectivity.
Inert biomedical devices with modular load-bearing function designed with peculiar multi-domain composite microstructures. The reference compositional system is Zirconia-Alumina with a prevailing overall composition of customizable zirconia or alumina. Examples of devices are 3D structures consisting of parts with differentiated functional properties, due to different composition/microstructure/architecture, and further functionalizable ex-post to favor and improve the stabilization of the implantation by newly formed bone in superior quantity and quality.
The constant demand for more powerful and energy-efficient electronic devices than existing ones is challenging scientists and companies to develop innovative solutions that can address such primary technological needs. Based on a recent scientific discovery made by our team we have developed a technology for superfast and extremely scalable logic and computing circuits with minimal energy losses, which has the potential to become the leading technology in the future world of largescale computing and telecommunication infrastructures.
The proposed technology takes advantages of the huge potentialities of the gellan gum microgels in the preservation of cultural heritage. Microgels are polymeric gels particles with the micro and nanoscale size, whose soft nature is due to the presence of the aqueous solvent inside the particle. For their small size, they can easily diffuse in the environment and penetrate in the porous structure of paper and wood to act as cleaner agent.
Geopolymers are synthetic inorganic polymers obtained from an aluminosilicate powder and an aqueous solution of alkaline hydroxides or silicates. The material is mesoporous and a multidimensional and functional porosity can be generated through the addition of fillers or the use of specific techniques.
The mix-design of the mixture, pure or composite, allows to change the chemical-physical properties of the final material, also thanks to the nucleation of zeolitic phases. Geopolymers also possess ion exchange and electrostatic interaction capabilities.
The current technology allows to achieve new macroporous superadsorbent polymeric materials able to remove toxic contaminants from water and soil showing excellent sequestering properties against arsenate As (V), chromate Cr (VI) and Borate B (III) ions. The material is obtained by radical cryopolymerization of the monomer 4'-vinyl-benzyl-N-methyl-D-glucamine and / or its mixtures with hydroxyethyl-methacrylate (HEMA).
Anthocyanins are antioxidant polyphenolic pigments produced by plants that are widely used in the food, cosmetic and pharmaceutical industries. The technology allows to obtain in a short time potato cell lines in which the production of highly acetylated and highly complex anthocyanins is increased in addition to other antioxidant polyphenolic compounds. The obtained cellular lines have a high production efficiency, comparable to the extraction of berries, but with the advantage of having an on-demand production which is not limited to seasonality.
We developed a procedure aimed at simultaneously treating thousands of C.elegans model organisms, from eggs to old adult, in liquid, in 96- or 384-well plates. This procedure can be used to perform drug and toxicological screening of millions of compounds, in very small volumes and on millions of animals. Thanks to easy handling, semi-automatic analysis can be performed using plate readers or High Content Screening instruments.
22q11.2DS(DGS) deletion syndrome is a rare and phenotypically variable multiorgan syndrome, currently without any cure. Our aim is to develop a standardized approach to formulate pharmacological products useful for clinical trials direct to prevent some serious clinical manifestations of adolescence and adulthood, such as neuropsychiatric and musculoskeletal diseases, or to eliminate or improve cardiovascular defects during embryonic development.
NIRS is a non-invasive technique for the human brain cortex imaging based on the measurement of the NIR light emitted by suitable optical sources placed on the patient head and backdiffused to the surface after passing through the brain tissues. NIRS monitors the percentage of oxygenated and reduced hemoglobin in the blood, and it allows the real time functional imaging of the brain cortex also in tomographic mode (Diffuse Optical Tomography - DOT).
The technology based on cell or tissue cultures is very useful for the production of bioactive compounds. These molecules, depending on the class they belong to, can be used in the food, pharmaceutical and cosmetic industry. In particular, the developed technology is addressed to the optimization of bioactive compounds in plant cell/tissue cultures having the biosynthetic pathway of the compound of interest.
INCIPIT technology allowed the implementation of a multifunctional, micro-structured and electroconductive therapeutic product to treat patients with myocardial infarction, the leading cause of death for cardiovascular disease. Current therapies (drugs, bypass, angioplasty) do not restore the functionality of damaged myocardial tissue.
The herein described technology aims at the development of a platform of injectable hydrogels for application as drug carriers for localized delivery or in the regenerative medicine field. The use of ad-hoc synthesized poly(ether urethane)s (PEUs) as hydrogel forming materials is a common property which characterizes all the systems belonging to this platform.
In the last years, genetics played a strategic role in the identification of therapeutic targets for complex diseases. Genetic studies identified thousands of variants contributing to disease onset and/or to the influence of measurable features (phenotypes) impacting health. The mechanism of action by which they modulate diseases and phenotypes is still unknown for the vast majority.
