a Quantitative analysis of viability of MDA-MB-231 breast cancer cells treated with PNIPAM-ppy-FA and Dox@PNIPAM-ppy-FA with different concentrations and with or without 808 nm NIR laser irradiation. b Fluorescence images of live/dead assay in MDA-MB-231 cells after treatment of PNIPAM-ppy-FA and Dox@PNIPAM-ppy-FA nanocomposites (60 μg/mL) with or without NIR laser irradiation. The live and dead cells are stained with Calcein AM (green) and Ethidium homodimer-1 (red). Scale bars are 200 μm
