The microrobot system has three key elements, including magnetic nanoparticles (MNP) loading probiotic neg 1917 (EcN @ MNP) spatial magnetic and hypoxia sensing, thermal logic circuit designed to bacteria control mCherry biosynthetic temperature and localization reporter, and NDH-2 enzyme-encoded enhanced anticancer therapy. Based on fluorescent protein-based imaging feedback, the microrobot showed good thermal sensitivity and active targeting to the tumor region
