Gold Nanoparticles: Their Application as i Antimicrobial Agents and Vehicles of Gene Delivery

Abstract: Antibacterial properties of gold nanoparticles with special reference to size and shapeAlthough gold nanoaparticles are not as strong a antimicrobial agent as silver nanoparticles, GNPs have been

“…Their values at 2θ was observed to be at 38.4°, 44.6°, 64.6°, and 78.3°for the indexing angles of reference planes (111), (200), (220), and (311), respectively ( Figure 6). Similar results match those found in the literature as well [12,54,66]. This analysis clearly revealed the spherical structure of synthesized GNPs.…”

“…The GNPs as well as the gold solution have very strong antimicrobial activities. The MIC The maximum antibacterial activity of the synthesized GNPs in doses of 25 μL/mL and 50 μL/mL of GNPs and 10 μL/mL of gold solution were recorded at 11 mm, 10 mm, and 9 mm, respectively, of the collected samples under study; in the literature, a similar result was found [12,66]. This confirms that higher doses of GNPs can exhibit a good antibacterial potential against the Salmonella strains which is gram negative when compared to gram-positive strains as confirmed [12,50,66] in the literature.…”

“…The triangularshaped AuNps as previously reported by Smitha and Gopchandran (2013) exhibit strong antibacterial activity against several bacteria compared to spherically-shaped AuNps. AuNps adhere to the membrane via electrostatic interaction and disrupt membrane integrity (Kundu 2017). They can cause leakage of intracellular components by generating holes in the membrane.…”
