Figure Lengend Snippet: Cell compatibility of CoPc‐Lig NPs. A) Cell viability of fibroblasts (black bars) and keratinocytes (white bars) exposed to different concentrations of CoPc‐Lig NPs for 24 h. B) Confocal images showing cell internalization of CoPc‐Lig NPs (0.5 mg/mL) by fibroblasts and keratinocytes. The dark areas in brightfield images represent CoPc‐Lig NPs, while the fluorescence channels show cell nuclei (Blue), and cell cytoskeleton (green).
