An efficient ultrasound-enhanced controllable release of biologically active trace elements on bioactive silica-gel-based material
The multilayered Silica@Zn-Sr@Silica nanospheres were fabricated by a layer-by-layer (LbL) assembly route, and controlled release of active trace ions can be enhanced by low-frequency ultrasound, which is potentially advantageous not only to multicomponent administrating but also to elicit synergistic effect for promoting tissue regeneration combined the trace ion activity with ultrasound physical stimulus.
