Researchers unveiled camouflaged nanorobots engineered to modulate macrophage behavior within neural tissue and promote regeneration. The devices are designed to influence immune cell polarization and spatial organization in injured neural environments, accelerating repair processes in preclinical models. The work, led by Guo, Wang and Jiang, integrates nanotechnology with immunomodulation and could inform future regenerative therapies for neurotrauma and neurodegenerative disease.
