MRS Bulletin Materials News Podcast · Dec 21, 2022 · 9m

In this podcast episode, MRS Bulletin’s Stephen Riffle interviews Alessandra Scagliarini, a professor of infectious disease at the University of Bologna, and Beatrice Fraboni, a professor of physics at the Department of Physics and Astronomy at the University of Bologna, about their electrical transistor assay that quantifies SARS-CoV-2 for antibodies. The purpose is to determine vaccine efficacy over time. The device is built with the semiconducting material poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The material not only transfers ion signals into electronic…
