  • investigation of osteoconductive and osteosteoinductive properties of implant materials in human and rodent mesenchymal stem cell and osteoprogenitor cultures  – 2D and 3D cultures on experimental surfaces and scaffolds and dynamic cultures (i.e. cultures stimulated with dynamic media flow),
test equipment:
  • scanning electron microscopy at room temperature,
  • electron probe X-ray microanalysis of element content and distribution with energy-dispersive spectrometry,
  • flow cytometry,
  • scanning laser microscopy – confocal microscopy,

comercial research:
  • chemical or low-teperature preparation of biological materials and hydrated polimers for their examination by means of scanning electron microscopy,
  • low-teperature preparation of biological materials and hydrated polimers for element analysis by means of X-ray microbeam techniques
Courses, trainings, workshops on:

- preparation of biologically-derived materials for scanning electron microscopy imaging and examination,

- preparation of biologically-derived materials for X-ray microanalysis,

- preparation of standards dedicated to quantitative X-ray microanalysis of biological materials,

- methods for quantitative analysis of elements by means of X-ray microanalysis in biology, 

- practical operation of the scanning electron microscope combined with energy-dispersive spectrometer for element analysis,

JU scientists to develop biological agricultural support solutions
The project “Interactions between plants and microorganisms in response to the presence of potentially toxic metals, metalloids and silicon (Si)” by Prof. Katarzyna Turnau from the JU Faculty of Biology won a grant from the Polish National Agency for Academic Exchange. The study aimed at replacing the widespread use of agrochemicals with biological agricultural support solutions will also involve researchers from Slovakia and Austria.
JU students will help people suffering from depression
Therapify is a mobile application designed to help depressed people. It was first conceived by Łukasz Pstrong, a graduate of the AGH University of Science and Technology in Kraków, and developed over the course of the last two years with collaborators from his university, the Jagiellonian University, and SWPS University of Social Sciences and Humanities in Warsaw.
Plakaty Demo Day II +
In January, we complete the project managed by CTT CITTRU as part of the program of the Ministry of Science and Higher Education - Incubator of Innovation +. We supported, among others, 18 research teams selected in the competition, that develop innovative technologies. Thanks to the funds granted by CTT CITTRU and hard work of technology transfer officers, pre-implementation research was financed, which increased the attractiveness of these inventions and investors interest in them. Take look at the gallery of posters for technologies, developed as part of the project. What do you think about it
