➀ Electrically activated ferroelectric nematic microrobots demonstrate controlled motion and assembly. ➁ These microrobots utilize the polarization coupling between ferroelectric liquids and solids. ➂ The study explores the effects of the fringing field profile on the microrobots' behavior. ➃ Ferroelectric nematic liquid crystal droplets exhibit electromechanical instability and fluid jets. ➄ The research contributes to the understanding of active matter and collective motion in complex systems.

1. Engineers at UC San Diego have developed microrobots that can navigate through the lungs to deliver cancer-fighting medication directly to metastatic tumors. 2. These microrobots, a combination of biology and nanotechnology, use green algae cells to swim and deliver drug-filled nanoparticles to lung tumors. 3. The treatment has shown improved survival rates in mice with lung metastases from melanoma, suggesting potential for future human clinical trials.

1. Researchers from the University of California San Diego have developed microrobots capable of navigating through lung tissue to deliver targeted cancer drugs. 2. These microrobots, constructed by bonding drug-filled nanoparticles to algae cells, have shown effectiveness in mice by slowing tumor growth and increasing survival rates. 3. The use of red blood cell membrane coatings on nanoparticles helps these microrobots evade the immune system, allowing for prolonged activity against tumors.
