Abstract
Plastics, which are pivotal in modern technological progress and have a broad range of applications, now pose a significant environmental and health risk globally. Despite their detrimental environmental effects, there is a lack in research on effective plastic removal and treatment strategies. Addressing this urgent issue necessitates the development of innovative and efficient materials and methods for removing plastics from contaminated environments. In this study, we utilized a microfluidic technique to create novel and eco-friendly asymmetrically structured micromotors made of glucose oxidase (GOx)/catalase (Cat) embedded in polyethylene glycol diacrylate (PEGDA). These micromotors are specifically engineered to efficiently remove substantial amounts of plastics from ecosystems. The microfluidic process enabled the production of micromotors with uniform yet asymmetric shapes through aqueous two-phase separation and UV polymerization. By incorporating functional nanomaterials, these micromotors can be customized for specific wastewater treatment needs. Our design utilizes GOx and Cat to consume glucose as fuel, generating oxygen microbubbles. These bubbles not only propel the micromotors but also capture suspended plastic nano/micro-particles, effectively removing them from aquatic environments. The high surface tension of the bubbles allows for the entrapment of plastics at their interface, facilitating their removal from the water. In addition, non-toxic nature of these GOx/Cat PEGDA micromotors makes them especially suitable for environmental remediation and biological applications, addressing the urgent need for environmentally benign solutions to plastic pollution.
