Timon Baltisberger is to receive the prize for the best master’s thesis in nanosciences at the University of Basel in 2022. In the prizewinning thesis, he proved that Vibrio cholerae bacteria inside a biofilm are more tolerant to various antibiotics than cultures grown in agitated liquid medium. The results help to improve our understanding of biofilms, which play a major role in nature and can lead to stubborn infections in humans.
