«Investigating Diphenylalanine-Graphene Interactions in Water Using Molecular Dynamics Simulations»

Διμελής Επιτροπή: Ιωάννης Ρεμεδιάκης, Αναστασία Ρισάνου

Περίληψη

Graphene (GF) has gained much popularity in recent years due to its unique properties with a wide range of applications. Except of the extensively studied field of electronics, scientists are finding ways of implementing graphitic surfaces in biomedical applications as well. More specifically, it has been proven that the design of peptide-graphene composites can aid in the manufacturing of thinner and more sensitive biosensors. One peptide of great interest for such applications is diphenylalanine (FF), the key structural motif of Alzheimer’s β-amyloid peptide. Understanding the mechanism of the formation of peptide layers on top of graphene is crucial for exploring their full potential.

In this diploma thesis, we study aqueous solutions of FF with and without graphene nanofillers through all-atom Molecular Dynamics simulations, utilizing both explicit and implicit solvent models. Our focus is on both the physicochemical behavior of the systems and the validation of the implicit solvent model. Therefore, we investigate the self-assembly mechanism of FF peptides in water and the effect of pristine graphene nanoflakes on this process, as well as the FF-graphene interface through the SPC/E explicit solvent model and the GBSA implicit solvent model. Starting with the bulk (reference) systems, in the absence of graphene nanoflakes, the self-assembly of dipeptides in the aqueous solution is driven by electrostatic interactions, hydrogen bonding as well as their high hydrophobicity. Aggregation of FF is observed, with similar structural characteristics from both explicit and implicit solvent models. In the nanocomposite system, diphenylalanine-graphene interfaces are formed, prior to the self-assembly of dipeptides. A number of FF covers the surface of the nanofillers, forming stable layers of specific thickness, due to electrostatic attraction. The rest of dipeptides start to self-assemble forming aggregates on top of them. Moreover, the diffusion of FF in water is affected by the graphene nanofillers with the dipeptides exhibiting higher mobility away from the interfaces. In the case of nanocomposite systems implicit solvent model revealed qualitative similar behavior, although further optimization and/or more efficient models are demanded.

Postgraduate Studies on Soft Matter Science & Engineering in the Department of Materials Science and Technology of the University of Crete

04 Απριλίου 2024

Call for Applications for Postgraduate Studies on

Soft Matter Science & Engineering

in the Department of Materials Science and Technology

of the University of Crete

The aim of the Soft Matter Science & Engineering Postgraduate Program is to provide students with the needed skills to pursue successful careers or further advanced studies in the highly interdisciplinary field of soft materials. The educational and research activities of the program provide an integrated approach and in-depth training, with emphasis on conducting innovative research in a variety of soft matter fields, including (but not limited to) synthesis and characterization, polymers, colloids, composites, interfacial properties, materials for energy, biomimetic materials, responsive networks, materials for biological or biomedical applications, eco-friendly and sustainable materials, recycling, rheology and processing. 

Successful completion of the Program leads to a Postgraduate Diploma (MSc) after 4 semesters of study that include mandatory attendance of courses (2 semesters) and submission and oral defense of a Master's Thesis (2 semesters). Internships will be offered in the summer period between the first and second year. The program is in English and requires full-time participation. As part of their training, postgraduate students assist in the instruction of undergraduate courses.

The tuition fees are 3.500€ for the entire program. Scholarships may be available.

Graduates of the first cycle of studies of any Institution have the right to apply for the program. International students should have a degree equivalent.

Eligible candidates should hold a degree in Sciences or Engineering. Good knowledge of English (B2 level and above) is required. Candidates who have not graduated during the application period will be considered, but possible eventual enrollment is subject to receiving their first degree until the end of October 2024.

The academic criteria that are taken into account for the selection, as defined in the Postgraduate Studies Regulations, include the undergraduate degree, recommendation letters, grades in courses relevant to the program, the senior thesis (if applicable), as well as the applicant’s relevant research or professional activity (if applicable).

Necessary supporting documents:

• Application
• Detailed CV
• Report of interests
• Diploma supplement
• Up to three (3) letters of recommendation
• Certificate of a good knowledge of the English language (B2 level and above)
• Any other document the applicant considers to be evidence of scientific excellence and quality.

The application must include an e-mail account, from which the applicant will be informed about the progress of his/her application.

Letters of recommendation should be sent directly from the authors to the postgraduate secretariat stratigis@materials.uoc.gr.

Deadline for submission of the application and supporting documents for the Postgraduate Program is set for May 24, 2024. The candidates will be informed about possible (online) interviews by May 31, 2024.

Applications and supporting documents are submitted exclusively online to the postgraduate secretariat stratigis@materials.uoc.gr before the deadline.

For more information, please contact the Secretariat of the Department of Materials Science and Technology, Mr. Ch. Stratigis (tel. +30 2810-394272, (stratigis@materials.uoc.gr) or the Director of Postgraduate Program on Soft Matter Science & Engineering, Prof. D. Vlassopoulos (dvlasso@materials.uoc.gr ).
