Andrei Vasile NASTUTA holds a doctoral degree in Physics and is currently serving as an Associate Professor of Physics and Biophysics at the Department of Biomedical Sciences, Faculty of Medical Bioengineering, University of Medicine and Pharmacy “Grigore T. Popa” Iasi. Over the course of a decade, he has been conducting teaching sessions and hands-on activities (in both Romanian and English) in the fields of Physics and Biophysics for the students enrolled in the Faculty of Medical Bioengineering.
Andrei Vasile NASTUTA founded and directs the Physics and Biophysics Education Research Laboratory (P&B-EduResLab), which is dedicated to strengthening the education of aspiring researchers in the field of physics and its various applications. The main topic addressed, but not exclusively, is “Atmospheric Pressure Cold Plasma Bioengineering,” with the indicated areas of focus being emphasized: The research focuses on the development and diagnosis of plasma sources, encompassing both electrical and optical diagnostic techniques. Additionally, the study explores the application of plasmas for surface modification. The investigation aims to understand the generation of reactive species, specifically reactive oxygen and nitrogen species (RONS), using optical emission spectroscopy. Furthermore, various characterization techniques are employed, including surface adhesion and energy analysis through contact angle measurements and assessment of mechanical properties. Surface roughness is evaluated using atomic force microscopy and optical microscopy. Other aspects such as biocompatibility and skin surface conductivity are also examined, utilizing skin conductance level and skin conductance response measurements. The individual possesses extensive expertise in the manipulation of plasma for various surface treatment processes, including activation, cleaning, functionalization, grafting, etching, and polymerization. This proficiency extends to diverse surface types, encompassing both organic and inorganic materials. Additionally, the individual has acquired substantial knowledge in the production of thin layers using magnetron or hollow cathode plasma systems, as well as the examination of properties exhibited by 3D printed polymer structures.
He has contributed more than sixty times to various national and international specialist conferences and is the author of more than forty research works (articles and book chapters). As a researcher, he was involved in over fifteen national and international scientific initiatives and four educational grants.
The research team at P&B-EduResLab is presently engaged in a project titled “Enhancing ink print adhesion and 3D printing properties of materials by using atmospheric pressure plasma jet” (Plasma4AdhesionPrint). This project, which is supported by a national research grant, involves a series of investigations focused on the application of atmospheric pressure plasma as a technological method for environmentally sustainable surface treatment of polymeric materials. The primary aim of this research is to improve surface adhesion by employing atmospheric pressure plasma jet (APPJ) treatment. This treatment is intended to enhance the ink-printing quality of plastic materials and promote stronger inter-layer adhesion in 3D-printed products.
