Radiosensitizing effect of AuNP and SAHA double treatments on cancer cells growing in 3D. The combination of AuNPs and SAHA significantly decreased the colony forming capability of A549, DU-145, PC-3 and MCF-7 cells in 3D cell cultures after 2 and 4 Gy irradiation compared to the control and to the individual treatments.
