PN-IV-P2-2.1-TE-2023-1281
MXEPEPMIN
Project Summary
The project MXEPEPMIN proposes the development of miniaturized electrochemical biosensors for fast, sensitive and selective detection of the lung cancer biomarkers, carcinoembryonic antigen (CEA) and epidermal growth factor receptor (EGFR), using novel functionalized MXene nanomaterials and peptides as bioreceptors. The functionalized MXenes provide a conductive layer which enhances the sensitivity of the electrochemical detection, and represent the support for the covalent binding of the receptor peptides. The resulting MXene-Peptide biosensors will display higher sensitivity and specificity, a better reproducibility and stability compared to traditional methods for early detection of lung cancer biomarker. The specific objectives of the project are: 1) the preparation of functionalized MXene with enhanced electrochemical properties; 2) the development of sensitive and selective MXene-Peptide electrochemical biosensors; 3) the integration of the MXene-Peptide biosensors in miniaturized devices for the non-invasive detection of CEA and EGFR in human saliva. This project will have an impact in the field of clinical applications for early-stage diagnosis and treatment of lung cancer.

The impact of the MXEPEPMIN project:
1) The estimated scientific results
The main goal of MXEPEPMIN is to develop modified interfaces that combines the properties of novel 2D- inorganic compounds with those of synthetic peptides as specific biorecognition elements. The main results of the project will be the innovative and miniaturized Peptides-MXene based bioanalytical tools for early detection of CEA and EGFR biomarkers that will be obtained. The developed biosensors are expected to display enhanced sensitivity, selectivity, antifouling and antimicrobial properties, as well as good reproducibility and detection of biomarkers in low sample volume. The proposed biosensors will be the basis for the development of a new detection methods for the CEA and EGFR lung cancer biomarkers at concentration values of pg/mL. The estimated results for the whole project are: 3 papers published in ISI Web of Science indexed international journals; the presentation of the results at least 6 scientific conferences; and 1 patent application.
2) The potential impact of the project on the host institution and the project team
The project will contribute to the visibility of the research teams from the host institution on an international scale by reporting the result in ISI WoS indexed international publications and presenting the results at scientific conferences and symposiums. The project leader and the research team members will gain experience in project management and multidisciplinary research as the team members have different fields of research, and will exchange scientific knowledge with each other and can help them have a more comprehensive view of scientific research for further projects. The project will contribute to the training of young scientists, in a prestigious research institution within Romania.
3) The impact over the scientific, technological, social, economic or cultural environment
The proposed method will lead to the development of new point-of-care sensing devices for biomarker detection and will represent an important scientific impact in the field of clinical applications. The MXene-peptides based biosensors will facilitate the sensitive, selective, fast and low-cost detection of lung cancer tumors. The developed detection format within this project could also be further adapted to other types of analytes by replacing the receptor peptide with one specific for other types of tumor biomarkers, or markers for other clinical conditions such as diabetes, inflammation or infections. Thus, the project will have a positive impact in the field of clinical applications and lead to further innovations that will improve early-stage detection and treatment of lung cancer and thus contribute to the improvement of human health.
