Abstract:
For the past century, the environment suffers from rapid deterioration due to the explosive development of chemical and pharmaceutical industries. Large quantities of drugs, personal care products, detergents, pesticides, food additives have been released in the aquatic system. The pollutants of emerging concern are not yet monitored and well regulated by authorities while there is an increased awareness of their impact on human health. The United Nations World Water Development Report 2018 states that “An estimated 80% of all industrial and municipal wastewater is released to the environment without any prior treatment, resulting in a growing deterioration of overall water quality with detrimental impacts on human health and ecosystems”. Advanced Oxidation Processes (AOPs) based on photocatalysis are the most powerful and viable alternative to the conventional wastewater treatment technologies that still have some limitations (e.g., high operation costs, energy consumption, or reduce efficiency due to the chemical stability of pollutants and/or the complexity of their degradation). Thus, the development of solar-driven catalysts with improved photocatalytic activity for the environment-friendly and facile treatment of aquatic systems remains an important target to environment remediation.

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:
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. Advanced materials and biomaterials for improving the quality of life (health, sport, education) because: ► a new nanocomposite material with graphene will be developed, for better medical treatments ► complex inter-/multidisciplinary studies will be performed, in order to elaborate and validate new standardized therapies based on advanced materials ►the development of a new perspective in dentistry, based on advanced theoretical and practical knowledge ► a research network will be developed which can ensure human resources for the top scientific research ► articles will be published in highly-ranked journals (ISI) ► research papers will be presented at international conferences ►valuable information will be disseminated among PhD/PostDoc students and researchers in the field of nanocomposite materials ►the equipments that will be purchased will develop the existing R&D infrastructure.
