Bravo, Sergio Vázquez-Estévez, Benigno Acea-Nebril, Cristina NúñezAbstractAdsorption of biomolecules onto nanoparticles surface in biological samples led to the formation of a bio-corona, it could modified the “identity” of nanoparticles, contributing to the determination of their toxicity and biocompatibility.Gel electrophoresis in combination with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was employed to qualitatively analyze and identify the human serum proteins adsorbed on the surface of three different nanomaterials stabilized with citrate: 10.02 ± 0.91 nm gold nanoparticles (AuNPs), 9.73 ± 1.70 nm silver nanoparticles (AgNPs) and, 2.40 ± 0.30 nm platinum nanoparticles (PtNPs). An exhaustive analysis and classification of all identified proteins related with their function were also developed.Graphical abstract
