Biocatalytic biobots brew beer better
Encapsulated yeast and iron nanoparticles enhance beer fermentation through self-propelled oscillatory motion and easy magnetic retrieval
Beer-brewing ‘biobots’ could boost the drinks industry by speeding up fermentation . Researchers in Czechia encapsulated yeast and iron oxide nanoparticles in a biocompatible polymer to create self-propelling biobots, which can be retrieved from beer samples magnetically – eliminating the need for filtration steps.
