摘要
Brain tumors have been proved challenging to treat. Here, we present a promising alternative by developing an implantable ultrasound-powered tumor treating device (UP-TTD) that electromagnetically disrupts the rapid division of cancer cells without any adverse effects on normal neurons, thereby safely inhibiting brain cancer recurrence. In vitro and in vivo experiments confirmed the significant therapeutic effect of the UP-TTD, with ~58% inhibition on growth rate of clinical tumor cells and ~78% reduction of cancer area in tumor-bearing rats. This UP-TTD is wireless ultrasound-powered, chip-sized, lightweight, and easy to operate on complex surfaces, with a largely boosting therapeutic efficiency and reducing energy consumption. Meanwhile, various treatment parameters could be tuned from the UP-TTD without increasing its size or adding circuits on the integrated chip. The tuning process was simulated and discussed, showing an excellent agreement with the experimental data. The encouraging results of the UP-TTD raise the possibility of a new modality for brain cancer treatment.
