Di-sulfide linked polyethylenimine coated gold nanoparticles (ssPEI-GNPs) of 20 nm size was prepared in order to deliver the genes to target site. DLS and TEM analysis demonstrated that the GNPs have average size of 13 nm in diameter. Upon coating the GNPs with ssPEI in the weight ratio of 1:3, the average hydrodynamic diameter of the ssPEI-GNPs was found to 19 ± 1.14 nm and a zeta potential value 41 ± 1.23 mV was observed. TEM analysis of ssPEI-GNPs demonstrated that the nanoparticles have spherical morphology. Thermogravemetric analysis of the prepared ssPEI-GNPs showed that the estimated composition of the ssPEI coated over the GNPs was approximately 5% (w/w). Gene expression capabilities of the nanoparticles were confirmed by fluorescent microscopy and luciferase assay, which demonstrated the transgene delivery capability of the ssPEI-GNPs. These results demonstrate that ssPEI-GNPs could be used as gene delivery agent.
