Annexin V/Death cell assay in MDA-MB-231 cells in a apoptosis and b necrosis. Bare HSA/CS, PSS-coated GNRs@HSA/CS, PSS/DOXO-coated GNRs@HSA/CS and DTX + PSS/DOXO-coated GNRs@HSA/CS hybrid NPs were irradiated at several power densities with a NIR 808 nm CW laser at 0.0 (white), 0.5 (blue) an 2.0 W/cm2 (red). Free DOXO, free DTX and free DOXO + DTX were used as positive controls, whereas untreated cells were the negative one
