Ultrasound‐Responsive Extracellular Vesicle‐Encapsulated Piezoelectric Nanoparticles for Chronic Inflammatory Pain Suppression
Chronic inflammatory pain is characterized by the long‐term coexistence of central sensitization and neuroinflammation. Electrical stimulation has been demonstrated to be an effective strategy for alleviating chronic inflammatory pain. However, implanted electrodes have limited lifespan and inevitably lead to tissue...
