Abstract:

The project proposes the development of an original topical formulation, with dual therapeutic action, resulting from the incorporation of synthetic (Nimesulide and Chlorhexidine) and natural (Boswellia serrata extract) anti-inflammatory and anti-infective agents in nanovesicles (Bilosomes), NS&CH-Bls@BSE, to improve delivery of the active compounds, optimizing biopharmaceutical properties, ensuring effective therapeutic results in treatment of inflammatory skin conditions and infected wounds, while reducing systemic side effects due to transdermal administration. Bilosomes, lipid nanovesicles enriched with bile salts, are stable structures that favor the penetration of active agents through skin layers by increasing permeability. The final formulation, NS&CH-Bls@BSE, and its components will be tested both physico-chemically and biologically (in vitro and in vivo). The proposed topical formulation will be carried out in interdisciplinary collaboration between researchers from INCDTIM - Romania (CO) and USMF Nicolae Testemitanu - Republic of Moldova (P), combining the expertise of the two teams. The relevance of the partnership consists in: developing an innovative product through joint research; the transfer of acquired know-how by CO to P and the access of P researchers to the CO infrastructure; strengthening collaborations and integrating P researchers into the scientific networks of which CO is a part, increasing the number of joint project proposals and the success rate.

Abstract:

The dramatic decrease in the exact sciences of Romanian students has determined us to come forward with new ways of raising their interest. This relatively modest interest could be caused by the classic way of teaching these STEAM subjects in the classroom, generally without adequate experimental support, which limits the optimal interaction of students with the materials proposed for study. The dynamization of the learning process and the opening of new appell in sciences, to a level at which choosing a career option in this field is a viable one for the younger generation. This can be successfully achieved only by involving institutions always in contact with scientific news and technological advances in various fields of STEAM disciplines. The objective of the project is: to support and promote an interdisciplinary education based on the integration of science and technology in Romanian schools, which will develop critical thinking, creativity, technological and problem-solving skills, preparing students for the challenges of modern society and the labor market. Direct beneficiaries of the project are: students, teachers and schools. 29 schools are involved, from 6 counties, from middle and high schools, from urban and rural areas, from schools with a theoretical but also technological profile, and two school centers for inclusive education; two schools with teaching in Hungarian and one school with teaching in German.

Abstract:

We propose an alternative to traditional diagnosis of infections based on surface-enhanced Raman scattering (SERS) which involves collecting a sample from the patient, which is further put in contact with a silver spot laser induced, resulting in scattering and recording the spectral fingerprint of the pathogen, if present. By comparing the obtained fingerprint with standard spectral fingerprints from existing databases, the pathogens may be identified at strain level within minutes. Obtaining an antibiogram is the final step, which can be assessed in maximum of a couple of hours. This method may enable an effective and targeted infection treatment, and may reduce significantly the mortality rate, especially in infants, given by the increasingly number of aggressive strains.

The proposed nanoscreening platform offers a unique approach that is different from other medical techniques utilized nowadays for the screening of pathogens in routine clinical work. It combines SERS for the ultrasensitive molecular fingerprinting of pathogens with microfluidics for their isolation. Moreover, we intend to comprehensively implement additional computational tools in order to achieve a full understanding of the pathogens’ mechanism of resistance. This issue will be pursued by using optimized, in-house developed statistical model for identification, discrimination and classification of pathogens and quantum chemistry molecular modelling tools. The main advantages of the proposed SERS-based nanoscreening platform are that it is rapid, label free (no use of antigens, receptors, dyes or other specific labels is required), cost-effective, reliable, portable and ultrasensitive.

Once we succeed to tackle the connection between the resistance behavior of antibiotic-resistant pathogens and their spectral fingerprint monitored in real time by using our proposed methodology, we will be able to move forward and to influence point-of-care routines for sepsis.

Abstract:

In this project we aim to develop and validate an experimental demonstrator for the label-free surface-enhanced Raman scattering (SERS) detection of pathogens within less than 15 minutes.

Thus, we propose a demonstrator, comprising a microfluidic flow-cell coupled to a flow system, and a portable/handheld Raman spectrometer for SERS detection of pathogens immobilized in the flow cell. This will lead to a rapid, ready-to-use system of detection that will provide rapid, high sensitivity and culture-free analysis of real biological samples.

We propose a label-free SERS–based alternative approach for detecting pathogens in a practical manner, by developing an experimental demonstrator that is based on the in situ silver NPs preparation in a microfluidic flow-cell and the handheld Raman spectrometer as detection tool. This innovative methodology is sustained by the research background of the candidate (specialized in vibrational spectroscopic techniques, mainly SERS and its analytical chemistry and biomedical applications), the partner's expertise, and the latest generation equipment. Eventually, the team members will be able to validate the developed detection methodology by using the handheld Raman spectrometer on real biological samples, in laboratory conditions.

The objectives of the project are developing the experimental setup, optimizing and validating the SERS detection methodology by using the developed device and finally, validating the experimental demonstrator and apply for a patent registration. As a final step of the development of the detection system, the analysis time will be reduced to less than 15 min.

The pathogens we will test are most common Gram-negative uropathogens, foodborne pathogens, Gram-positive enterococci, skin pathogens, and pathogenic fungi which cause complications in immunosuppressed patients.

Thus, after project implementation the TRL will reach a level of 4 on the TRL scale.

Abstract:

The bio-sensing for bacteria detection is currently explored by using various sensing materials and approaches but it is still a challenge to find an alternative to the conventional protocols, based on microorganisms’ cultivation. This project proposal provides an ultrasensitive and selective, but simple, rapid and inexpensive bacteria detection and identification method by using a receptor-free and innovative immobilization principle of the biomass. Raman spectroscopy, which combines the selectivity of the method with the sensitivity of the surface-enhanced Raman scattering effect (SERS), is used in correlation with Principle Component Analysis (PCA) in order to develop biosensors for pathogenic microorganisms. Most common pathogenic bacteria will be tested by applying an original immobilization protocol and the in situ synthesis method of the SERS-active nanostructures. The specific molecular information gathered from the spectroscopic data will be uploaded and analyzed by means of advanced statistical methods, with the final goal of creating an appropriate protocol which will be used on complex biological samples. The rapid pathogens identification and differentiation between multiple species, down to strain level will be carried out by means of SERS-PCA bio-sensing. Furthermore, the efficiency of multiple classes of antibiotics on bacteria viability will be investigated by SERS in order to obtain rapid and precise diagnostic and targeted treatment.
