Maciej Jerzy Głowacki is an alumnus of the Gdańsk University of Technology. He graduated with honors from the Faculty of Mechanical Engineering (B.Eng., 2017) and the Faculty of Electronics, Telecommunications and Informatics (M.S., 2018). Since 2014 he has been continuously actively involved in a research carried out at the Department of Metrology and Optoelectronics. His previous scientific activities include a deposition of antibacterial hydroxyapatite coatings on titanium substrates used in implants, and an examination of nanocomposite materials using the polarization sensitive optical coherence tomography with spectroscopic analysis. Currently he studies Control, Electronic and Electrical Engineering at the Doctoral School of the Gdańsk University of Technology, where he carries out research on optoelectronic sensory microsystems utilizing color centers in diamonds. In the QUNNA project, Maciej is responsible for a fabrication, modification and optical characterization of nanometric diamond structures containing the color centers. The most frequently produced systems include nanodiamond suspensions prepared via sonochemical methods and thin diamond layers deposited using ablation techniques. The prepared samples are used by all research teams in the consortium for, among other things, an examination of nonlinear optical effects in structures based on optical fibers, an investigation on the magnetic properties of the color centers, and tests for detection of biological matter in aqueous environments. Maciej examines the physical properties of the diamond structures using the following measurement techniques: UV-VIS, fluorescence, and Raman spectroscopy, polarization microscopy, scanning electron microscopy (SEM), and optical coherence tomography (OCT).
