Coomassie-stained SDS-PAGE gel lanes for protein coated 20 and 200 nm GNPs. FBS is a combination of various proteins. The lanes “20 nm serum and 200 nm serum” show a band for protein bound to the GNPs suggesting the presence of protein corona. The samples incubated with plain DMEM did not show any protein bands (data not shown)
