Biofabrication of silver nanoparticles using Andrographis paniculata

Green Synthesis of Silver Nanoparticles Using Commiphora caudata Leaves Extract and the Study of Bactericidal Efficiency

“…Ajitha et al reported the same value 3 keV for Ag NPs using Plectranthus amboinius leaf through biosynthesis Ag NPs [34]. According to Kotakadi et al, strong silver signal along with weak oxygen, chloride and carbon peak, which may originate from the biomolecules that were bound to the surface of the Ag NPs, indicates the reduction of silver ions to elemental silver [35].…”

Green synthesis of silver nanoparticles from marigold flower and its synergistic antimicrobial potential

“…In such a situation, biological approach appears to be very appropriate. Natural material like plants, bacteria, fungi, yeast, are used for synthesis of silver nanoparticles (Rangnekar et al, 2007;Ahmad et al, 2013;Sumana et al, 2013;Kotakadi et al, 2014;Vidhu and Philip, 2014).…”

Efficient and robust biofabrication of silver nanoparticles by cassia alata leaf extract and their antimicrobial activity

“…Though there are many reports regarding antimicrobial activity of AgNPs biosynthesized by plant materials, in most of the cases the plant extract showed minimum or no inhibition, whereas the synthesized AgNPs showed minimum to moderate and good to excellent activity [15,[17][18][19][20][21][22]. The past studies reveal that different concentrations of AgNPs are more effective against S. aureus than E. coli [35], whereas Ruparelia et al [36] determined the AgNPs against four different strains of E. coli and three different strains of S. aureus.…”

“…There are a number of approaches available for the synthesis of silver nanoparticles, for example, reduction of solutions [1], chemical and photochemical reactions [2], thermal decomposition of silver compounds [3], radiationassisted [4], electrochemical [5], sonochemical [6] and microwave-assisted processes [7], use of bacteria [8], fungi [9] and enzymes [10], and recently via the green chemistry route [11][12][13]. The use of environmentally benign materials like plant leaf extract [14][15][16][17][18][19][20] for the synthesis of silver nanoparticles offers numerous benefits which are compatible with various pharmaceutical and biomedical applications. The presence of some toxic chemicals adsorbed on the surface of the nanoparticles that are synthesized by chemical methods may have adverse effect on the biomedical applications.…”
