Magnetically boosted 1D photoactive microswarm for COVID-19 face mask disruption

Abstract

Most single-use face masks are made of synthetic plastics, thus their disposal poses a direct threat to wildlife as well as potential ecotoxicological effects in the form of microplastics. Here, the authors introduce a 1D magnetic photoactive microswarm capable of actively navigating, adhering to, and accelerating the degradation of the polypropylene microfiber of single-use face masks.
