(a) Fluorescence microscope images of HeLa cells on 1-μm-wide gold (Au) nanodisk arrays labeled with a cell membrane-impermeable dye (Calcein AM). (b) Scanning electron microscope images of fixed cells on a substrate. (c) Overlay of the green-box-designated region seen in (b) with (a). (d) Fluorescence microscope images of HeLa cells on 2-μm-wide gold (Au) nanodisk arrays labeled with a cell membrane impermeable dye (Calcein AM). (e) Scanning electron microscope images of fixed cells on a substrate. (f) Overlay of the green box-designated region seen in (b) with (a). (g) Scanning electron microscope image of single Hela cell on 2-μm-wide Au nanodisk array substrate. (h,i) Simulation results of surface temperature at the gold nanodisk array (1-μm wide) interface in water. Scale bars: (a-f) 100 μm, (g) 20 μm.
