Another research line is the biofunctionalization of the micro or nanoparticles of various materials: polymers, paramagnetic or gold particles. These are used in the detection of certain antigen or antibody, biomarkers from biological human samples or in the selective marking of certain cells such as subpopulations of T lymphocytes.
To confirm and assess the success of the biofunctionalization process, during, as well as upon the completion thereof, we use advanced characterization methods: RAMAN spectroscopy, infrared Fourier transform spectroscopy with attenuated total reflectance – FTIR-ATR, atomic force microscopy – AFM, scanning electron microscopy – SEM, transmitted electron microscopy –TEM, spectrophotometry UV-VIS, electrochemical impedance spectroscopy. The collected data are processed, interpreted and correlated.
