Two dimensional semiconductors for ultrasound-mediated cancer therapy: the case of black phosphorus nanosheets

With black phosphorus (BP) as an example, the first two-dimensional (2D) semiconductor based sonosensitizer (Au@BP nanohybrids) was fabricated. Under ultrasound irradiation, Au@BP nanohybrids can generate 1O2 in deep tissues and eradicate tumors with high efficacy. This platform paves the way for the application of 2D semiconductors in sonodynamic cancer therapy.
