Fig 7. Identification of AuNPs-capping metabolites.

Fig 7

NPs solution was centrifuged and the NPs were collected and washed by PBS two times prior to extraction using methanol and sonication for 15 min. The extracted metabolites were analyzed by GC-MS and compared to those extracted from NP-free supernatants. (A) Metabolites were identified from NPs and shared between F180 and MCF7 cell lines. (B) Unique metabolites identified from NPs developed from MCF7 versus those developed from F180. The data display the mean of the percentage of the metabolites ± SEM of three replicas. The table on the left represented the comparison between the identified metabolites from NPs to those identified in Figs 2 and 6.
