“…However, a new characteristic absorption of spherical silver nanoparticles appeared at 408 nm. corresponding to the characteristic surface eplasmon resonance of metallic Ag NPs [29][30][31]. The Ag NPs further confirmed by the TEM image shown in Figure 3(a) and Figure 3(b) revealed that the monodispersed Ag NPs had an average diameter of about 10nm and a good dispersion.…”

To prepare antibacterial fabrics with simple approach, wood pulp/viscose fibers and amino-capped silver nanoparticles (Ag NPs) solution were utilized to form Ag Nps-coated wetlace nonwove fabric. Characterization of the Ag Nps and prepared wetlace nonwoven fabric was performed in virtue of TEM, UV-vis, XRD, ICP-AES, FESEM, EDS mapping and antibacterial test. FESEM and EDS characterizations demonstrated the hierarchical and uniform coating of high-density Ag NPs on wood pulp fibers, and antibacterial test indicated the excellent antibacterial activity of prepared wetlace nonwoven fabric.

Au nanoparticles (NPs) of controlled morphology have been synthesised through an eco-friendly biogenic method utilizing the aqueous fruit extract of Garcinia cowa at room temperature. The bio extract executes dual role of reducing agent and stabilizing agent to add excellent stability to the synthesized colloidal Au NPs. The variation of particle size and morphology of Au nanostructures with respect to the quantitative part of the bio-extract were studied. After microscopic and spectroscopic characterization, further application of the Au NPs synthesized via green method in the preparation of complex organic molecules was studied. The Au NPs were employed as homogeneous catalyst in coupling of substituted indole and aromatic aldehydes to yield bisindolylmethanes, which are known precursors of anti-cancer bioactive molecules. In addition, microwave irradiation makes the coupling reaction more sustainable with very short reaction time of 40 secs.
