Laser scanning confocal microscopy (LSCM) images of Hep G2 cells cultured with
free PLMSNs, PGC-PLMSNs meshes and PGC-PLMSNs meshes exposed to laser
irradiation (NIR 808 nm, 0.6 W/cm2). For each panel, images from left
to right show the Hep G2 cell nuclei stained by DAPI (blue), cell membrane
stained by DIO (green), and particles fluorescence in cells (red). The scale bar
is 50 μm.
