A two-step wet chemical method is described for the preparation of spherical silver nanoparticle-decorated flower-shaped zinc oxide (ZnO@Ag) heteronanostructures using a newly designed redox-active poly(ionic liquid)(PIL), poly(1-vinyl-3-butylimidazolium ascorbate) (P[VBuIm][As]). The first step is the generation of ZnO nanoflower using P[VBuIm][As] in water followed by its decoration with in situ...
A water-soluble amphiphilic peptide-poly (1-vinylimidazole) [Boc-Cys (PVim)-Trp-OMe] bioconjugate is synthesized by ‘grafting from’ technique based on thiol-mediated radical polymerization. The attachment of fluorescein isothiocyanate (FITC) at the N-terminus of the peptide moiety of the bioconjugate results in the generation of fluorescent bioconjugate [FITC-Cys (PVim)-Trp-OMe]. MALDI-TOF-MS analysis...
Herein, the synthesis of polyhedral oligomeric silsesquioxanes (POSS) end-functional poly(1-vinyl imidazole) (POSS-PVim) hybrid using thiolated POSS in combination with AIBN as the radical initiator is described. Owing to its amphiphilic nature, such a hybrid could self-aggregate into primary micelles with PVim corona and a core containing POSS crystalline aggregates in water. POSS-PVim hybrid molecules...
Gold nanoparticles (GNPs) are known to be a very good catalyst. Also, the anchoring of GNPs with stabilizing ligands is essential for surface modification, tuning of size and shapes, and to prevent from aggregation in suspension. But the effect of ligand on the catalytic property of ligand-capped GNP is yet to be explored in detail. In this paper, we perform an in-depth study of effect of ligands...
