Björn Agnarsson

Research Engineer at Nano and Biophysics

As a member of Biological Physics, I am involved in the development of new analytical methods and tools for detecting and tracking nanoparticles on surfaces and in bulk (extracellular vesicles, viruses, liposomes and metallic particles). My main research interests include, but are not limited to, micro and nanofabrication, optical sensors, plasmonics and general interdisciplinary work.
