Modifying upconverting nanoparticles with polyelectrolyte multilayers

Chembio 2019 in Helsinki

University of Turku was well represented in the Chembio 2019 event in Helsinki 27.-28.3.2019. Isabella Norrbo from our group and Maarit Karonen from NCRG presented their research in Materials in Nature seminar by FinTAC ry. In addition, Marica Engström from NCRG presented her research in the session by the chromatography society of Finland.

Great job from all of you!
