During the period 01.08.2022 to 21.10.2022, PhD student Valentina Vorona from the Laboratory of Soil Microbiology at the Institute of Microbiology and Biotechnology and National Center for Materials Study and Testing, UTM, had a visit to Joint Research Center in Ispra, Italy where she continued the previous investigations on nanoparticles - cell bacteria interaction.

During the visit at Joint Research Center, Ispra, in Nanobiotechnology Laboratory, a variety of instruments were learned to use for characterization of nanomaterials. Nanoparticles like Fe3O4/PVP, CoFe2O4/PVP, CoFe2O4/PEG, MgFe2O4/PVP, and MgFe2O4/PEG were investigated for size distribution, morphology, structural properties and chemical analysis.

The interaction of magnetic ferrites nanoparticles with bacterial cells based on in vitro biocompatibility studies was investigated using techniques like TEM, SEM, CLM, AFM and characterize the adsorption of nanoparticles on the bacteria surface.

Valentina also studied the toxicity of the nanocomposites on different concentration for  rodococci bacteria. In the last day of stay in Ispra, Valentina presented her results at the online Unit meeting, where the obtained results were discussed.

vlad jrc 2022

During his four-months visit, Vladimir learned a variety of instruments to use for characterization of nanomaterials. Nanoparticles like ZnO and GaN were investigated for size distribution, morphology, structural properties, chemical analysis for further application as antibiotics drug delivery system for sinusitis treatment. Techniques like XPS, TEM, DLS, UV/Vis spectroscopy were used to characterize both qualitatively and quantitatively the binding of antibiotics on the nanoparticles surface.

During the visit Vladimir investigated inorganic nanoparticles for potential applications in drug delivery system for sinusitis treatment. Nanoparticles with or without magnetic properties were used to encapsulate different types of antibiotics using strategies like chemical (carbodiimide or hydrazine chemistry) or electrostatic binding.

During the NanoMedTwin partner workshop in Ispra from September 8-9, he presented the results with a final conclusion on the work done during the last visit.

During his three-months visit, Vadim was trained to operate the Scanning Electron Microscope, Raman spectroscopy and XRD equipment, and to interpret the obtained results. The investigated materials, ultrathin layers of semiconductor compounds, were obtained by Vadim at the „D.Ghitu” Institute in Moldova, in the framework of his doctoral thesis. The obtained results demonstrate the feasibility of the aerosol deposition and spin coating deposition, as cost-efficient methods for obtaining ultrathin layers of high-quality semiconductor compounds which will be used in the development of UV radiation detection.

Upon his return home, Vadim held a seminar and presented all the newly acquired results. Besides the improvement of English language, he had the possibility to improve his science communication and gain new valuable skills. He said: „The NanoMedTwin project was very necessary and useful in gathering information about photodetectors obtained by different methods. It gave me the opportunity to accumulate professional experience and information for my doctoral thesis. In order to make science more attractive in Moldova, there is a need for such research projects, where young generation can be involved at international level.”

Mihail Batiri (PhD student from the Technical University of Moldova)
4 April – 4 August 2022
University of Bristol, UK

Mihail Batiri, PhD student from the Technical University of Moldova, spent  4 months (April – August) at the University of Bristol under the guidance of Dr. Andrei Sarua. His visit focused on the exfoliation of 2D layered materials like SnSe, SnSe:Bi, SnS, and SnS2 and investigation of optical properties.

During his visit, Mihail had the opportunity to study and train on using different measuring equipment and also work with experienced specialists from the University of Bristol, thus making new and valuable contacts.

The main goal of the visit was achieved, by using different exfoliation techniques Mihail obtained very thin layers of SnS, SnS2 and SnSe materials with thicknesses of 5-25 nm and lengths of 1-10 um. The thin layers were characterized by SEM/EDX, TEM, AFM and Raman Spectroscopy. Through photolithographic processes, metallic contacts were deposited and later on the electrical properties of SnS thin layers were studied.

Mihail mentioned “NanoMedTwin project is an opportunity for young researchers at the beginning of their careers to improve their skills and gain valuable experience for their future research. During the visit, I participated in various courses and seminars, I had the opportunity to visit the Electrochemistry laboratory at the University of Southampton and under the guidance of Dr Andrei Sarua, I was training in various measurement techniques. The obtained experience and results are highly valuable for my doctoral thesis and I had the unique opportunity to make new and valuable contacts with whom to develop a longstanding collaboration”.  

Tatiana Galatonova (MSc student at the Technical University of Moldova)

During her visit, Tatiana developed new skills in the field of biosensing: working principle of biosensors based on signal detection; surface functionalization and multiplexed measurements for increased selectivity; DNA detection peculiarities, etc.  Beside training at KTH, before accessing lab work, Tatiana passed the two-week training at Uppsala University on how to work with the system and the biosensor, calculate the maximum effective concentration of the solutions, and use them in practice. The lab work was continuously supervised at the weekly meetings and recent literature review was being assimilated during the Journal Clubs.  As a Master student, Tatiana has followed all the activities at TUM online, and additionally was following the Bio-nanotechnology course at KTH BB2400 that contains: tutorial (assignments, ASS; 1.5hp), lab exercise (Lab; 1.5hp) and written examination (TEN1; 4.5hp).

Returning home by mid of June, Tatiana said: „Organizing projects of such a level as NanoMedTwin is an opportunity for young students at the beginning of their careers. The collaboration and mobilities through such high-level institutions as the Royal Institute of Technology develop our research skills and ignite our interest to go further in this field with a new baggage of ideas, knowledge, and experiences. Last but not least are the formation of the connections obtained on trips with the scientists who have been working in this field for years and are ready to guide and consult you even after finishing the mobility. Certainly, the NanoMedTwin project is a success for the Republic of Moldova and has opened a new vision for me in science.”

Simon Busuioc (MSc student at the Technical University of Moldova)
15 January – 15 June 2022
Royal Institute of Technology, Sweden

Simon Busuioc is a Master student at Microelectronics and Nanotechnology, and during his visit at KTH he was involved in the investigation of the optical properties of the transparent wood. He got an introduction to integrating sphere, atomic force microscopy, laser-based particles analyser, and other characterization tools. Every two weeks Simon was attending meetings with Dr. Ilja Sytjunov and Dr. Hui Chen, where practical results were discussed and a short-term working plan was developed. Simon attended the course “Colloids and Colloidal Principles for Applications” between 21.03.2022 – 20.05.2022 and several seminars, including “Carla Camp Open House” organised by Photonics Sweden between 11.05.2022 – 12.05.2022, where the photonics as a future technology was discussed.

Back at TUM with inspiration and new vision, Simon said: „During this internship I gained a unique and much needed working experience, not only in a new, unfamiliar branch of my main field of study, but also in new environment, besides people with different perspective regarding working practices. This gave me an opportunity to improve myself as a person and as a researcher. Even if it was tedious from time to time, I consider my visit to be worthwhile.”
