Abstract:

The main objective of the project is to design a new generation of stochastic sensors based on modified graphene materials for the fast screening of biological fluids (whole blood, saliva, urine) as well as of tissue samples, in order to diagnose faster the upper gastro-intestinal cancer. In this regard, a panel of biomarkers specific to this type of cancer was selected to be analyzed using stochastic sensors. In the final stage, statistic evaluation of correlation between the panel of biomarkers found in biological fluids and tissue samples using stochastic sensors will be performed, providing the information about the possibility of diagnosis of this cancer without performing the biopsy, all only based on screening tests of biological fluids and complementary imagistic noninvasive techniques. The panel of markers proposed to be analysed is the following: - the marker that is known to be supressed during gastric and gastro-esophageal carcinogenesis - p53, it will be used as a banchmark. The other biomarkers that will be used are the following: maspin, heparanase (an endoglycosidase that is a major component of the extracellular matrix), MMP-2 and MMP-9 (two matrix metaloproteinases), HER-2 and CD26/DPP4 (a surface T cell activation antigen). Graphene materials dopped with nitrogen and boron will be synthesized and use as paste unmodified or modified with fructans, ionic liquids or aptamers for the design of stochastic sensors. The stochastic sensors will be fully characterized electrochemically, and validated against a minimum of 200 real samples from confirmed patients: biological fluids and tumoral tissues will be used for validation, but also for developing of a faster, noninvasive method of screening for fast diagnosis, avoiding in this way the biopsy.

Abstract:

While dental cements development led to the emergence of new materials that meet the changing needs of dentists and together with innovations in delivery devices, have been cementing procedures faster, easier and more predictable. Functional these cements must withstand masticatory stress; maintain integrity in the oral and transferring occlusal forces from the fixed prosthetic restorations, dental and periodontal tissues.

Current resin cements are commonly used in dentistry commercially available inhibitors of their versatility, resistance and high compressive strength, low solubility and high aesthetic quality. Their main disadvantages are difficult removal of excess, working technique sensitive, high cost and difficult restoration cemented adhesive removal - most often sectioned into pieces before restoring be loosening. Graphene is considered to be the “thinnest and strongest material in the universe” and therefore it has remarkable physical and chemical properties, including superior Young’s modulus (1 TPa) and tensile strength (130 GPa). Recent studies have shown that graphene can be used as nanofiller and can dramatically improve the properties of polymer-based composites at a very low loading (0.1-5 wt. %). The aim of this project is to develop a technology for obtaining a cementing material, biocomposite, based on biocompatible polymers and graphene nanofillers of modern treatments and standardized bioglasses for cementing caries prevention effects.

Abstract:

Altering living environment (through air, water and soil pollution) is one of the most complex problems of mankind due to its repercussions, in most cases irreversible and chronic, with negative impact on the most precious attribute of man: its health. As a result of anthropoid activities, some metal ion (like copper, nickel, cadmium, chromium, lead, mercury, zinc and others) reach water sources. These items are considered particularly dangerous pollutants, due to the imbalances and diseases they can cause (even at low concentrations) and because of their cumulative effect in different organs, since the body is unable to eliminate them by conventional methods. The current project proposal is motivated by the increase threat of heavy metal pollution and due to the requirements for the development of new, cheap and sensitive detection devices. The major objective targets the development and validation of a laboratory technology for the fabrication of a low cost sensing electrochemical platform for selective detection of lead ions concentration from aqueous solutions. Our main goal is to take a nanocomposite graphene based material from a state of raw potential up to a point where we can exploit the graphene unique electrical and optical properties, by integration of modified electrodes in novel electronic systems that can revolutionize multiple industries, especially the sensor applications, with direct beneficial impact in health and life sciences. The research team targets to take use of the high sensitivity and selectivity of an already existing modified electrode obtained in our group (from the surface area modification of a metallic, gold electrode with a new type of nanocomposite material based on chitosan and N-doped graphenes) in order to build a selective electrochemical detection platform for lead ion concentration from different water sources.

Abstract:

The major scope of this project is to develop and validate a laboratory technology for the detection of two leukemia biomarkers: 8-hydroxy-2’-deoxyguanosine and 8-nitroguanine, in blood and urine samples. In order to achieve this, we will design, implement and test a demonstrative model of stochastic sensor, which can provide improved services in the area of public health. Other important achievements of the project will be: (i) cost-efficient and reproducible graphene synthesis; (ii) full characterization of graphene properties, as sensing layer on different substrates; (iii) studies of detection mechanisms and effect of grafene surface modifications. This will enable to develop sensors with ultra-low detection limits for biomarkers relevant to human health, in laboratory conditions. In this way, we will use the knowledge generated by basic research in the sensor area, for developing a higher level of technological maturity.

Stochastic sensing creates a totally new approach, allowing the same systems to be used in vitro and in vivo. Advantages over current capabilities: (i) single-molecule resolution; (ii) detection in real-time with broad spectrum detection; (iii) such technology eliminates the need for microarrays and multi-step labeling assays. Market size: vast applicability in biomarkers, metabolomics, proteomics, genomics.

Biomarkers are diverse in their conformations, requiring higher design complexity of receptors and sensors for successful sensing. In order to achieve these, two major objectives are proposed:

O1: Developing of lab-validated technology for the detection of two leukemia biomarkers;

O2: Increase the capacity of the two Research Institutes to generate new lab technologies and to provide them to economic agents.

Major expected result: technology validated in the lab for two leukemia biomarkers.

Abstract:

The aim of the present project proposal is to develop innovative research in the field of graphene-based nanomaterials as advanced and functional materials. Additionally, the project will tackle aspects regarding the supramolecular behavior of graphene with porphyrin derivatives. The graphene-porphyrin assemblies will be formed by two different approaches – one that involves the oxidation of graphite and its reduction in the presence of nitrogen containing molecules and the other method involves the porphyrin mediated direct liquid-phase exfoliation of graphite. The two types of graphene-based nanomaterials are expected to present different electronic properties with direct implication on their application as chemical or electrochemical sensors of hydrogen peroxide – a known stable oxidative stress marker. In this respect, the peroxidase-like activity of the graphene-porphyrin assemblies will be assessed by the oxidation reaction of a peroxidase substrate. This project will also open new directions for exploring more of their possible applications.

Abstract:

The growing need for energy requires development of new energy sources/carriers and more efficient utilization of energy. Hydrogen is the ideal energy carrier due to its natural abundance and non-polluting nature.

The development of hydrogen storage technologies for mobile applications still requires overcoming some technical barriers.

Different hydrogen storage paths have been envisaged: from the classical storage technologies, namely pressurization and cryogenic liquefaction, to the solid phase storage in metal hydrides, or physisorbed on a solid surface (metal-organic frameworks, covalent organic frameworks) and the organic liquid hydrogen carrier (LC) under ambient conditions.

Chemical hydrogen storage can became competitive if the storage material fulfils some requierements: high gravimetric and volumetric hydrogen content under ambient conditions, energy-efficient reversible charge and discharge, the absence of byproducts, long-term stability, low toxicity, easily available at a large scale and at a low price. The challenge is to find suitable organic carriers.

Formic acid is a promising candidate for reversible hydrogen storage. The aim of this project is to study formic acid decomposition/formation using a new type of catalysts: metallic nanoparticles confined in metal-organic frameworks, to exploit the nanoparticles confinement and the nanoscale properties for reactions of formic acid dehydrogenation and carbon dioxide reduction under mild conditions.

Abstract:

In modern dentistry, both the early prevention of tooth decay and the development of new and efficient restorative materials are generally targeted. Although tremendous efforts have been made in promoting oral hygiene and fluoridation, the prevention of early caries lesions are still challenges for dental research and public health. Recent studies have indicated that nanotechnology might provide novel strategies in dentistry.

Graphene consists in a one-atom-thick planar sheet of sp2–bonded carbon atoms arranged in a hexagonal lattice. Graphene is considered to be the “thinnest and strongest material in the universe” and therefore it has remarkable physical and chemical properties, including superior Young’s modulus (1 TPa) and tensile strength (130 GPa). Recent studies have shown that graphene can be used as nanofiller and can dramatically improve the properties of polymer-based composites at a very low loading (0.1-5 wt.%).The results so far reported in the literature indicated that graphene/polymer composites are promising multifunctional materials with significantly improved tensile strength and elastic modulus, electrical and thermal conductivity. Despite some challenges and the fact that carbon nanotubes/polymer composites are sometimes better in some particular performance, graphene/polymer composites may have wide applications in dentistry due to their outstanding properties and the availability of graphene in a large quantity and at low cost.

Within the BIOGRAF project we plan to develop: ► a new nanocomposite material based on biocompatible polymers and graphene to be used in dental restorations ► new ex vivo tests to identify the host reaction to this material, in relationship with some biologic risk indicators. The final aim of the project is to develop modern and standardized therapies of caries lesions through the development of the novel nanocomposite material based on biocompatible polymers and graphene.

The present research project fits very well into the research domain 7. Materials, processes and innovative products since a new nanocomposite material with graphene will be manufactured which will fulfill the bio-safety criteria and have biocompatible properties with the local cellular environment. By its specific objectives BIOGRAF corresponds to the research thematic 7.1.6.

Abstract:

DONTAS project presents the research, development and innovation of new tools, like surgical methods and techniques by using metal implants coated with smart composite layers based on advanced nanotechnology for medical applications. More specific, nanostructured phosphates (nanoPHOs), such as nano hydroxyapatite (nanoHAP) incorporating different additions of silicon as an osseopromotive agent, as well as magnesium and zinc requested for bone metabolism are synthesized and structural, morphological and biological characterized. Further smart composites, made of said nanoPHOs incorporated into natural polymers (collagen type I and/or chitosan) are developed to mimic the characteristics of natural bone. In addition, nanoPHOs are incorporated into synthetic polymers (PMMA or poly-Bis-GMA) for comparison with the above ones. Our preliminary results indicate a remarkably difference among morphologies of various DONTAS composites ranging from particulate matters to fibers mineralized with nanoPHOs. Also, metal implants are realized by a strong cooperation in DONTAS consortium, formed of two prestigious universities and two important national institutes, as well as a small and medium sized enterprise (SME). The metal implants are advanced processed to reach the surface characteristics to be well osteo integrated in bone. Furthermore, the surface of implants is functionalized by coating with DONTAS composite layers to efficiently promote the bond of the implant to the bone. This inventive project tackles the bioactivity of the above new composites assembled as scaffolds on implants (rods, intramedullary rods or plates), which will be thoroughly examined in cell cultures of osteoblasts. DONTAS surgical tools and smart composites will have large medical applications for repairing and replacement of bone in orthopedic surgery and in reconstructive medicine.

Abstract:

Graphene-based materials have recently attracted considerable interest both from the experimental and theoretical scientific communities. Graphene is a monolayer of sp2 hybridized carbon atoms which are packed into a honeycomb crystal structure. Due to their exceptional thermal and mechanical properties as well as high electrical conductivity, graphene sheets have a variety of applications in battery, field-effect transistors and electromechanical resonators. Their applicability as biosensors has now started to emerge, due to significant advantages over the classical electrodes, such as electrocatalytic effect, enhancement of mass transport and high effective surface area.

This project proposal brings up novelties through the original method used to obtain nanostructured material (graphene-metal nanoparticles composite) as well as through the way of its application (detection and degradation of pharmaceutical pollutants). This project has a multidisciplinary research area. The research activities within this project will provide: (a) new approaches for preparation of graphene-metal nanoparticles composite; (b) explanations about the intriguing properties associated with graphene-metal nanoparticles composite; (c) experimental solutions related to the assembly of metal nanoparticles on graphene platelets; (d) application of graphene-metal nanoparticles composite in electrocatalytic detection of two pharmaceutical pollutants: carbamazepine and captopril
