Swimming protein microtube motors capture virus-shaped fluorescent nanoparticles

Abstract

Hemagglutinins (HAs), spike proteins of influenza virus, were fixed on luminous polystyrene beads to make HA-immobilized fluorescent nanoparticles (HA-FNPs). The protein MTs with an exterior surface of fetuin and an interior surface of catalase (Fet/Cat MTs) were self-propelled in aqueous H2O2 solution by spouting O2 bubbles. They captured molecular HAs and virus-shaped HA-FNPs efficiently.
