(a) 3D fluorescence spectra of Pt NCs. Insert is the photograph of Pt NCs under 365 nm UV irradiation. (b) TEM pictures of Pt NCs and (c) corresponding size distribution histogram. (d) Confocal microscopic photographs of K562, BV173 cancer cells, and normal PBMC cells after cultured with Pt NCs for 4 h. DAPI is employed to stain the cell nuclei emitting blue fluorescence, and Pt NCs show the green fluorescence (the scale bar is 20 μm) (reprinted major modification with permission from [186], Copyright 2018, Elsevier).
