Editors of the journal Applied Surface Science have bestowed the Frans Habraken Best Paper Award 2021 on Dr Katarzyna Gajos from the JU Faculty of Physics, Astronomy and Applied Computer Science for her paper entitled "Surface density dependent orientation and immunological recognition of antibody on silicon: TOF-SIMS and surface analysis of two covalent immobilization methods".
The award commemorating Professor Frans Habraken, the long time editor of Applied Sufrace Science has been presented annually since 2014 to the first or corresponding author of the best article published in this journal in the preceding year. The journal editorial board selects the winner based on such criteria as the novelty, originality, readability and scientific importance of the paper.
is based on research conducted by the team from the Marian Smoluchowski Institute of Physics, JU, consisting of Dr Katarzyna Gajos, Klaudia Szafraniec, Prof. Andrzej Budkowski, in collaboration with Dr Panagiota Petrou from the NCSR DEMOKRITOS, Athens. The studies conducted with the use of TOF-SIMS secondary ion mass spectrometry allowed the identification of dominant orientation of antibody molecules depending on the density of their layer on biosensor surface. As the antibodies’ orientation is of key importance for the antigen recognition, the research can help to improve the effectiveness and sensitivity of biosensors by optimising the methods of coating biosensor surface with antibodies.
The research was funded from the PRELUDIUM 11 grant by the National Science Centre.
Katarzyna Gajos graduated with distinction in Biophysics from the Jagiellonian University in 2013, within the framework of the Interdisciplinary Studies in Mathematics and Natural Sciences. She took up doctoral studies at the JU Faculty of Astronomy and Applied Computer Science under the supervision of Prof. Andrzej Budkowski, obtaining a PhD degree in Biophysics in 2017. She currently works as an assistant at the Department of Molecular Biophysics of the Marian Smoluchowski Institute of Physics, JU.
Research interests of Dr Katarzyna Gajos include biosensor surfaces, as well as biomolecular micropatterns and layers for biomedical applications. She applies various surface sensitive techniques for complex analysis of biomolecular layers on surfaces, especially TOF-SIMS secondary ion mass spectrometry. In 2018 she won START scholarship from the Foundation for Polish Science.
