Characterization of formulated gold nanoparticles. (A) UV–Vis Spectra obtained for gold nanoparticles and DEPC treated gold nanoparticles. (B) UV–Vis Spectra of DEPC treated gold nanoparticles (Au NPs), PEG capped Au NPs (Au—PEG) and MiRNA coated PEG capped Au NPs (Au–PEG–MiRNA). (C) FTIR spectra for citrate capped AuNPs (bottom) and MiRNA–PEG (top) capped Au NPs represent the binding of NH2-PEG-SH molecule on the surface of AuNPs. (D) Transmission Electron Microscopy (TEM) image obtained for PEG coated gold nanoparticles inset: histogram indicating particle size.
