When coupled with fluorescent light, the NanoSight Nanoparticle Tracking Analysis system enables the analysis of exosome samples to provide information of various distinct subpopulations of vesicles by labeling with specific antibodies tagged with a fluorescent reporter. Katarzyna Psonka-Antonczyk is a post-doctoral fellow in the Biophysics and Medical Technology group within the Department of Physics. Her interests include the characterization of nanovesicles (exosomes) with sizes ranging from 30 to a few hundred nanometers secreted by cancer cells to the extracellular matrix. Knowing the concentration of secreted exosomes can facilitate estimation of the secretory abilities of cells and can help in further sample preparation. NTNU NanoLab is a cross faculty, strategic initiative with the objective to coordinate and promote nanoscience and nanotechnology at NTNU(NorwegianUniversity of Science and Technology).
