Abstract
Artificial micro/nanomotors possess the capability to navigate intricate environments in accordance with a premeditated blueprint. Hybrid-propelled micromotors may present an efficacious approach in addressing scientific research quandaries. In this context, ferric oxide magnetic nanoparticles (Fe3O4 MNPs) are chosen as catalysts to be encapsulated within lipid vesicles (LVs) due to their superior quality and cost-effectiveness. The external magnetic field induces the aggregation of Fe3O4 MNPs within the LVs, resulting in the formation of an asymmetrical structure that promotes the catalytic reaction of hydrogen peroxide, producing oxygen to propel the movement of Fe3O4@LVs micromotors. The magnetic-fuel dual drive enables the Fe3O4@LVs micromotor to move 1.3 times faster than the LVs alone. Additionally, the magnetic field offers the advantage of controlling the direction of motor movement and facilitating retrieval for practical applications. This dual drive micromotor exhibits exceptional stability and reusability in aqueous solutions, underscoring its immense potential for future applications.
