Functionalized Graphene Derivatives: Antibacterial Properties and Cytotoxicity

Table 2

Binding Energies (BE) and deconvoluted peaks (%) for C1s of GO.

Peak BE (eV)	C1s At. %	Functional groups
284.4	59.0	C-C
285.4	16.0	C-OH
286.6	14.0	C-O
287.7	7.0
289.0	4.0	C(O)O
290.7	2.2	π-π

π-π: means the π-bonding orbital and the π-antibonding orbital.
