Early Life and Education
Born in Greece, Vassiliki Papadimitriou cultivated an early interest in science, shaped by the rich cultural and intellectual heritage of her homeland. She pursued her academic journey at the University of Athens, where she earned her PhD in Biology in 1996. Her education laid a strong foundation in biochemistry, which she later applied to her research in microemulsions and nanotechnology. Her rigorous academic training equipped her with the skills to tackle complex scientific challenges, setting the stage for a prolific career at the NHRF’s Institute of Biology, Medicinal Chemistry, and Biotechnology.
Research Contributions at the National Hellenic Research Foundation
Vassiliki Papadimitriou has been a cornerstone of the NHRF, serving as a Research Assistant Professor. Her work focuses on nanoemulsions and microemulsions, which are critical in applications ranging from drug delivery to agricultural innovation. These systems involve dispersing tiny droplets of one liquid within another, stabilized by surfactants, to create stable mixtures with unique properties. Her research has explored how these systems can encapsulate bioactive compounds, enhancing their stability and efficacy for various applications.
One of her notable studies, published in 1994, investigated small angle X-ray scattering (SAXS) measurements in water-in-oil (w/o) microemulsions containing enzymatic systems like trypsin or lipase. The study revealed that the presence of enzymes reduced the aqueous core radius of small reverse micelles, providing insights into enzyme behavior in confined environments. This work, co-authored with researchers like Aristotelis Xenakis and M.P. Pileni, has been foundational in understanding enzyme activity in microemulsions.
Another significant contribution was her 1993 study on the proteolytic activity of α-chymotrypsin and trypsin in anionic and cationic microemulsion systems. By examining parameters like pH and water content (expressed as the molar ratio wo = [H2O]/[Surfactant]), she elucidated how the polarity of the reaction medium influences enzyme activity. These findings have implications for developing efficient drug delivery systems and biocatalytic processes.
Key Projects and Patents
Vassiliki Papadimitriou’s research extends beyond academic publications to practical applications. She has been involved in several high-impact research projects funded by national and international programs. For instance, between 2010 and 2013, she coordinated a National Strategic Reference Framework (NSRF) project titled “Development of nanoemulsions as new materials for managing phytoprotective products.” With a budget of €449,040, this project aimed to reduce environmental impact by developing sustainable nanoemulsion-based solutions for agriculture.
In 2013, Papadimitriou co-authored a patent (OBI, 20130100305) titled “Biocompatible nanodispersions as media for encapsulating bioactive substances with phytoprotective activity.” This patent, developed with colleagues A. Kalaitzaki and A. Xenakis, underscores her commitment to translating research into real-world solutions, particularly in sustainable agriculture.
Her international collaborations include a 2006–2008 Cyprus-Hellenic project on the quality and stability of virgin olive oil, focusing on the role of endogenous enzymes and antioxidants. She also participated in a 2010–2014 CAPES program with Brazil, studying lipase activity in nanobiotechnology, further highlighting her global influence.
