Measurement of surface roughness of Ti-GO-Ag

	Ra (nm)	Rq (nm)	Rz (nm)
CON	3.30±0.36	4.50±0.29	44.6±4.3^a
G20	5.36±0.32	6.75±0.3	45.4±4.15^a
G50	7.19±0.33^a	9.32±0.39^a	118±14^b
G80	7.21±0.36^a	9.8±0.37^a	148±17
G100	10.6±0.4	13.5±0.44	116±13^b

Note: There is no statistical difference between the same letters in the same column (^a>0.05, ^b>0.05).

Abbreviations: CON, control; Ra, arithmetic average roughness; Rq, root mean square roughness; Rz, maximum height of contour; Ti-GO-Ag, titanium-graphene oxide.
