Biohybrid micro/nanorobots that integrate biological entities with artificial nanomaterials have shown great potential in the field of biotechnology. Here, the magnetic plant biobots (MPBs) were fabricated by employing tomato-callus cultivation engineering in the presence of Fe3O4 nanoparticles that are capable of active movement and directional guidance under a transversal rotating magnetic field. The MPBs enabled rapid and efficient removal of chlorpyrifos (approximately 80%), a hazardous nerve gas agent that causes severe acute toxicity, and recovery using an external magnetic field. The eco-friendly plant biobots described here demonstrate their potential in environmental applications.
