Microplastics – Microrobot Photocatalytic Degradation Procedure Described

The May 19, 2021 abstract of an ACS Applied Materials and Interfaces article by researchers with Check Republic University of Chemistry and Technology https://pubs.acs.org/doi/full/10.1021/acsami.1c04559 describes “… an active photocatalytic degradation procedure based on intelligent visible-light-driven microrobots with the capability of capturing and degrading microplastics ‘on-the-fly’ … The robots with hybrid powers carry built-in photocatalytic (BiVO4) and magnetic (Fe3O4) materials allowing a self-propelled motion under sunlight with the possibility of precise actuation under a magnetic field inside the macrochannels. The photocatalytic robots are able to efficiently degrade different synthetic microplastics, particularly polylactic acid, polycaprolactone, thanks to the generated local self-stirring effect in the nanoscale and enhanced interaction with microplastics without using any exterior mechanical stirrers … this proof-of-concept study using microrobots with hybrid wireless powers has shown … the possibility of efficient degradation of ultrasmall plastic particles in confined complex spaces …” #Microplastics @VSCHT
