A fresh new academic year has started with some fresh new people: the motivated BSc students had a flying start, rolling their lab coat sleeves already at the beginning of September and having their work done quickly and effectively. Me, Isabella and Ari are supervising their work, which luckily doesn’t require much overseeing since the students are smart and super self-directing. We warmly welcome Nina, Samu and Saara to carry out their BSc labs here at IMC.

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!
