Bacterial biofilms are considered the primary cause of huge economic losses, from medicine due to medical implants’ failure to large infrastructure due to enhanced pipe corrosion. Therefore, their eradication is highly desirable. Here, mganetic photocatalytic CoFe2O4/Ag microrobots for effective eradication of biofilms in both open space and hard-to-reach area is proposed. The low-cost and scalable preparation of CoFe2O4/Ag microrobots opens a new route toward the formulation of dual-mode-driven microrobots for environmental applications.
