Abstract:

In recent years, terrorist attacks primary based on releasing explosives and chemical warfare agents in the public happened frequently which makes it imminent to develop chemical sensors for the high selective and sensitive detection of warfare agents (WAs). Chemical warfare agents include blood agents, blister agents, and nerve agents including sarin and VX. Considering sarin’s gas high toxicity, DMMP (dimethyl methylphosphonate), an organophosphorus compound, is widely used as its simulant in the laboratory because of its similar chemical structure and much lower toxicity. Because the use of chemical warfare agents are impossible to predict or prevent, is required to design and synthesized of novel and improved materials that allow developing of more fast sensing systems with high selectivity, low-cost and on-site portable. Perovskite materials with outstanding properties have become significant candidates for developing platforms of the detection of toxic agents. Thus, the aim of the WAsSens project is development and testing a technology validated in the laboratory namely, a SH-SAW sensor, using undoped and Co or Sn doped ABO3 perovskite ceramics materials (A = Y; B = Mn) , obtained through low cost and environmentally friendly processes. To achieve the aim of the project, the overall objectives are: (i) Obtaining of perovskite structure through sustainable and green processes; (ii) Deposition of perovskite materials on quartz substrate in order to achieve thin films; (iii) Design, achievement and testing of SH-SAW sensor used for selective detection of the sarin gas simulant - DMMP; (iv) Dissemination of the research results. Project outcomes will materialize by advanced synthesis technologies, production processes and innovative products, and also in creating mechanism for implementation of scientific results in production. The expected outcomes will consist of innovative technologies and demonstrative models, in order to validate the proof of concept (TLR).

Abstract:

The project aim is to obtain a new adaptive system for mixing and dispersing a new innovative colloidal solution based on an organic decontamination matrix combined with several types of nanoparticles, which will be used for chemical, biological and radiological (RBC) decontamination of the surfaces of various technical equipment, vehicles, and terrain. The project starts from a decontamination solution (DS) developed as experimental model (TRL2) proved to be an effective DS for the decontamination of radiological agents, used for operationally decontamination of techniques, vehicles and terrain. TRL 2 was tested for the radiological decontamination efficiency with Am, Sr-I, Cs radionuclides. A project objective is to upgrade the existing decontamination solution (DS) tested and validated on radiological agents and make it suitable for chemical and biological warfare agents (C/BWAs) decontamination. The novelty consists in introducing nanoparticles with high efficiency against RBC agents, into DS matrix existing and make it behave like a singular colloidal complex. The new innovative colloidal solution (Nanodec RBC) obtained will be tested on CWAs (soman, mustard gas) and on BWAs (B. anthracis, B. cereus, B. subtilis, Streptococus aureus, Streptococcus pneumonia, E. coli, Pseudomonas aeruginosa, Klebsiella pneumonia). Another objective consists in development and realizing an adaptive mobile system for mixing and dispersion the Nanodec RBC, equipped with flow command – control software. The demonstration model (TRL4) will be a complex integrated system which will be designed, developed, tested on real WAs and validated its functionality. In order to meet the project goals a consortium of 3 partners with complementary facilities was constituted: 1 National R&D Institute for Microtechnologies (IMT Bucharest/CO); 1 research centre - Scientific Research Centre for CBRN Defence and Ecology (CBRNDESRC/P1 ) and a university - Military Tehnical Academy (ATM/P2).

Abstract:

This project proposes to obtain and validate "Point-of-Care" (POC) methods and kits for early diagnosis of SARS-CoV-2 infection. The aim is to develop original solutions for: viral RNA detection kit using LAMP isothermal amplification, anti-SARS CoV 2 antibody detection kit, viral antigen detection kit and a rapid test kit by multiplexing the system (for schools, institutions, points border). The kits will be of the "sample-to-answer" type, a plastic cartridge that supports a microfluidic system on paper. The proposed methods are cheap (3-4 Euro / piece), fast and precise (the LAMP method of isothermal amplification of nucleic acids is qualitative at the level of the "golden method" - rtPCR). Nasopharyngeal exudate and saliva (recently approved by the FDA) will be used as biological samples. Validation will be done on clinical trials by reference to the classical rtPCR method. By implementing the viral RNA detection kit for the saliva sample, Romania can become the first country in the world to introduce pandemic testing at home. The proposed solution may have a decisive effect in reducing SARS CoV2 infection, but also with a media effect in the international press and the scientific community.

Abstract:

Pesticide pollution of the environment is an actual acute problem, with expansion on a global scale and tends to rise. These contaminants are released into the air, water and soil from where are taken by organisms. By ingestion, organophosphorus pesticides get in human and animal body where they cause serious diseases such as irreversible damage to the immune system, cancer, genetic disorders. For the safety and security of the population, devices and advanced techniques for pollutants detection and monitoring in food and agriculture, are necessary.

The project PESTI-SENZ meets these needs and proposes the development of micro-biosensors based on lead-free piezoelectric materials, undoped and doped with different ions (Na, K, Bi, Zr) with selective properties and high sensitivity for the detection and monitoring of pesticides in agriculture and food.

Piezoelectric biosensors are being increasingly investigated because such devices allow direct label-free biological detection by monitoring target molecules in real time.

Detecting and tracking the compound of interest is very important in order to study the function and behavior of biological systems. In this sense, the purpose of PESTI-SENZ project is to get the environment friendly piezoelectric materials (lead free) and deposited to different substrates in order to be used to build FBAR-type piezoelectric arrays microsensor, functionalized with sensitive biomolecules for detection of organophosphorus compounds in aqueous media.

The main objective of the project is films and membranes obtaining based on piezoceramic materials free lead, in order to make devices for analysis and detection of biochemical compounds using innovative laboratory processes and technologies. The specific objectives of the project will pursue solving important theoretical and experimental issues which will contribute to the development of micro-sensors devices which incorporates demonstrator device based on new nanocrystalline piezoceramic with similar characteristics like PZT, and will provide guarantee of a safe exploitation environment.

Methodologies, materials and techniques used in project take into consideration requirements and international standards regarding environmental protection, avoiding the potential damage of property, natural resources, research staff and population health.

The project research team aims to merge skills and complementary expertise of consortium partners, to develop innovative technologies to achieve high efficiency for a sensing device with global applications.

The original aspects of the project, partners expertise combined to achieve a specific aim correlated with the current needs of modern society, provides the foundation for national research network consisting of multidisciplinary teams capable to collaborate synergic and complementary to exploit the extensive research results designed to lead to the realization of a device to ensure safe operation without adverse effects on human health.

Also we propose that the scientific and technical results that we obtain to bring added value to national and international scientific and, as well economic value at least at the national level in the first stage.

Scientific and technical activities carried out within the project by the consortium members will be widely disseminated among national and international scientific community through scientific papers, participation in specialized scientific conferences, patents, presentations at meetings of business people.

Abstract:

Globalization of terrorism became a reality that can not be disputed, a threat to national and international security and, thus, a phenomenon under the responsibility of the entire international community. Terrorist threat, theatres of operations with explosive traps everywhere, with the possibility of using biological weapons of various viruses, drugs, etc are a constant threat to the civilian population, unwittingly victim of varied interests. It is an ongoing concern of many laboratories in the world to detect traces of explosives in the atmosphere, in order to minimize the risks arising from them. To avoid or prevent serious incidents that could endanger people's lives, EU adopted new security rules. These rules apply to security checkpoints at airports, the senior public institutions, in the cultural and artistic events with massive participation, etc. However, there are situations in which all efforts to prevent terrorist acts are not sufficiently effective, creating holes that are exploited by potential attackers. Therefore, rapid detection of explosive compounds is of great interest given the need to prevent any human casualties and material damages caused by their use in different ways and for destructive purposes. The principle SENSOREX will bring an additional performance in the field of detection devices for dangerous substances with the low response time, high specificity, greater functionality and last but not least a low production price. Practical relevance of the project subject is to develop innovative products and manufacturing processes that underlie the development of sensitive, selective, reliable and low cost sensors detection of explosives. Appearance is very important from the perspective of efficient procedures for prevention of terrorism threats by using them in areas where existing equipment besides being very expensive, are almost impossible to use due to ergonomic aspects, reducing processing time suspicious persons and packages various strategic points and last but not least reduce additional costs. The main objective of SENSOREX project is to develop through this national partnership, a sensor with high sensitivity detection of explosives traces . Implementation status of this sensitive platform will be a sensor – demonstrator model tested and calibrated with low response time, high sensitivity and specificity, easy to use and interpreted by a non-specialist user and not least a low cost. Progresses that SENSOREX project brings through its results are: innovative methodologies for obtaining titanium dioxide films and molecularly imprinted polymers; creating scientific premises for serial production of a device with high sensitivity to reduce the most important barriers to personal and group security; final product of the project, sensor – demonstrator model, by its future implementation in production strategy of the private company, partner in this project, it will cover a hole on external and internal market of the profile products.
