Objective: Gold nanoparticles and nanoliposomes are effective new technology in delivering the bioactive agents and enhancing their performance by increasing the bioavailability. The goal of the present study was the formulation of liposome for the use as a carrier for nanogold conjugated with acyclovir (ACV), an antiviral drug, to enhance ACV delivery. Methods:The gold nanoparticles were used as a capping agent for ACV and sodium citrate was used as reducing agent for the gold. Transmission electron microscopy was used for characterization and to study the morphological and structural properties of drug-metallic nanostructures. Nanoliposomes were formulated using different molar ratios of a positive charge inducer (stearyl amine) or a negative charge inducer (diacetyl phosphate), lecithin, cholesterol and Span 60.Results: Gold nanoparticles with a particle size of 10-20 nm were formed. This small size of the formed particles has a clear effect in reducing the gold nanoparticles toxicity and enhancing the cellular uptake. The amount of sodium citrate used in this preparation influences the size of the gold nanoparticle. The present study employed 1% trisodium citrate that contains a carboxylic group and this carboxylic group works as a reducing and capping agent to synthesize ACV-gold nanoparticles conjugate. Liposomal formula F6 had the highest entrapment efficiency approaching 42%, the low particle size of 160 nm, and zeta potential of 43.5 mV. Conclusion:It is evident from the study that the liposomes can be used as a carrier of ACV conjugated with gold nanoparticles. This new strategy could be used successfully in the treatment of viral infection.
