Laboratory of Nanohydroxyapatite (LabOFn) is a group of scientists from the Department of Biotechnology and Bioprocess Engineering and the Laboratory of Biomedical Engineering of the Faculty of Chemical and Process Engineering. We build and develop technologies for synthesizing and applying modified hydroxyapatite nanoparticles.

The team is developing the technology for the precipitation of hydroxyapatite nanoparticles initiated by members of the team and Prof. Tomasz Ciach. Currently, we focus on two aspects of obtaining hydroxyapatite particles: control of particle morphology and size (in batch processes) and functionalization of particles, regardless of their morphology and size, including preparing drug carriers (directly in production processes or post-processing).

In addition to scientific cooperation and expertise in issues related to hydroxyapatite for medical applications, we offer a wide range of hydroxyapatite nano- and microparticles with known properties designed for a wide range of applications. Feel free to contact the manager or team members!
