====== Magnetoelectric Nanoparticles ======

[[Electrostimulation]] is regarded pivotal to promote repair of [[nerve injury]], however, failed to get extensive application [[in vivo]] due to the challenges in noninvasive electrical loading accompanying with construction of biomimetic cell niche. 

Zhang et al. demonstrated a new concept of magneto responsive electric 3D matrix for remote and [[wireless]] Electrostimulation.
By the preparation of magnetoelectric core/shell structured Fe3 O4 @BaTiO3 NPs-loaded hyaluronan/collagen [[hydrogel]]s, which recapitulate considerable magneto-electricity and vital features of native neural [[extracellular matrix]], the enhancement of [[neurogenesis]] both in cellular level and [[spinal cord injury]] in vivo with external pulsed magnetic field applied is proved. The findings pave the way for a novel class of remote controlling and delivering electricity through extracellular niches-mimicked hydrogel network, arising prospects not only in [[neurogenesis]] but also in human-computer interaction with higher resolution
