Weltweit werden Anstrengungen unternommen, das Coronavirus SARS-CoV-2 zu bekämpfen. Impfstoffe und schützende Masken sind dabei von zentraler Bedeutung. Empa-Forscher Peter Wick, Leiter des Particles-Biology Interactions-Labors in St. Gallen, äussert sich im Interview zu Antikörperstudien, die für die Entwicklung eines COVID-19-Impfstoffs entscheidend sind und die nächste Generation von textilen Schutzmaterialien, die Coronaviren inaktivieren oder gar abtöten.
Derzeit wird fieberhaft nach einem Corona-Impfstoff gesucht. Eine Antikörperstudie, an der Ihr Team beteiligt war, lieferte nun Hinweise zur Immunität gegen das Virus. Welche Lehren können Sie aus den Ergebnissen ziehen?
