(A,B) AFM images of GT-AuNPs and GT-AgNPs-NRG respectively, showing formation of spherical nanoparticles. AFM topographic images were recorded at AFM (Agilent 5500) instrument operated in tapping mode with silicon nitride cantilever. (C) TEM image of GT-AuNPs-NRG recorded at Tecnai G2 20 S-TWIN instrument. (D) UV-vis spectrum of GT-AuNPs-NRG showing characteristic surface plasmon resonance band at 540 nm. UV-visible spectra were recorded at UV-vis spectrophotometer (Evolution 300, Thermo Scientific) in aqueous medium. (E) FT-IR spectra of GT alone is compared with GT-AuNPs. (F) Comparative FT-IR analysis of NRG alone and GT-AuNPs-NRG. The spectra were obtained by using FT-IR spectrometer (Shimadzu Kyoto, Japan).
