Comparison of mean spectra of agNPs and internalized agNPs.
Notes: Macrophages were exposed to agNPs, agNPs with a complex Pc, or agNPs with a Bsa Pc at a concentration of 25 µg/mL for 2 hours. Intracellular AgNPs were then identified, and spectra were averaged to produce mean spectra. Intracellular spectra (red) were then compared to initial AgNP spectra (blue).
Abbreviations: NPs, nanoparticles; PC, protein corona; BSA, bovine serum albumin; PVP, polyvinylpyrrolidone.
