Highly Efficient In Vivo Cancer Therapy by an Implantable Magnet Triboelectric Nanogenerator

In this work, a nanogenerator‐controlled drug delivery system (DDS) for use in cancer therapy is successfully established. A new magnet triboelectric nanogenerator (MTENG) is fabricated that can guarantee the contact and detach cycle between the two friction layers and effectively increase the TENG output, up to 70 V after implantation. Using a special structural design, without the commonly used spacer, this contacting‐mode MTENG can ensure a...
