Fig. 2. Confirmation of in vitro reduction occurring en route.

Fig. 2

a Spectral intensity of light scatter from MCF-7 cells treated with Au–PEG clusters (n = 44 spectra), as distinct from untreated MCF-7 cells obtained through hyperspectral enhanced dark field imaging. b Corresponding enhanced hyperspectral darkfield image mapping of nanoparticles generated through Au–PEG treatment to MCF-7 cells with negative filtering with untreated MCF-7 cells (Supplemental Fig. 1e) to ensure no false-positive nanoparticle mapping. Scheme (c, d) with representative TEM images describing the reduction of ionic Au–PEG clusters (c), upon their interaction with cells (d).
