Curcumin coated gold nanoparticles: synthesis, characterization, cytotoxicity, antioxidant activity and its comparison with citrate coated gold nanoparticles

Objective(s): Biological applications of gold nanoparticles have limitations because of the toxic chemicals used in their synthesis. Curcumin can be used as reducing as well as capping agent in synthesis of GNPs to eliminate the cytotoxicity. Conjugation of curcumin to gold also helps in increasing its solubility and bioavailability. Materials and Methods: Here we report synthesis of gold nanop...

Origanum vulgare mediated green synthesis of biocompatible gold nanoparticles simultaneously possessing plasmonic, antioxidant and antimicrobial properties

Purpose The leaves and flowering stem of Origanum vulgare contain essential oils, flavonoids, phenolic acids and anthocyanins. We propose a new, simple, one-pot, O. vulgare extract (OVE) mediated green synthesis method of biocompatible gold nanoparticles (AuNPs) possessing improved antioxidant, antimicrobial and plasmonic properties. Materials and methods Different concentrations of OVEs were...

THE GREEN SYNTHESIS OF GOLD NANOPARTICLES USING THE ETHANOL EXTRACT OF BLACK TEA AND ITS TANNIN FREE FRACTION

Abstracts: nanoparticles. All the extracts were used separately for the synthesis of gold nanoparticles through the reduction ofaqueous AuClgold ions to gold nanoparticles. The ethanol extract of black tea and its tannin free ethanol extract produced goldnanoparticles in the size ranges of 2.5-27.5 nm and 1.25-17.5 nm with an average size of 10 nm and 3 nm, respectively.The prepared colloid gol...

Rapid synthesis and characterization of Gold and Silver nanoparticles using exopolysaccharides and metabolites of Wesiella confusa as an antibacterial agent against Esherichia coli

Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...
