- ItemA poly(3-hydroxybutyrate)-chitosan polymer conjugate for the synthesis of safer gold nanoparticles and their applications(Royal Society of Chemistry, 2018) Silvestri Daniele; Waclawek Stanislaw Witold; Sobel Bartłomiej; Torres Mendieta Rafael Omar; Novotný Vít; Nguyen Nhung Anh Huynh; Ševců Alena; Vellora Thekkae Padil Vinod; Müllerová Jana; Stuchlík Martin; Petrangeli Papini Marco; Černík Miroslav; Varma RajendraA facile and eco-friendly approach is developed for the synthesis of a poly(3-hydroxybutyrate)–chitosan (PHB–chit) polymer conjugate, which is an ideal material for the synthesis of safer gold nanoparticles (nAu). The synthesized products are characterized by various electron-based, optical and spectroscopic techniques including the catalytic activity and the stability/toxicity of nAu. In contrast to the conventional synthesis approaches, the use of PHB–chit results in generation of a highly stable and size-controlled nAu material that exhibits important catalytic activity towards the reduction of 4-nitrophenol (4-NP) to 4-aminophenol, and at the same time shows no toxicity against living bacterial systems such as Escherichia coli or Staphylococcus aureus. The synthesis route reported herein would inspire future developments that circumvent toxicity issues of relevance to living systems while performing common catalytic experimentation.

- ItemDevelopment of ZnO Nanoflake Type Structures Using Silk Fibres as Template for Water Pollutants Remediation(MDPI AG, 2020) Rao Jagajjanani; Korumilli Tarangini; KP Akshaykumar; Waclawek Stanislaw Witold; Černík Miroslav; Vellora Thekkae Padil VinodWe have fabricated ZnO nanoflake structures using degummed silk fibers as templates, via soaking and calcining the silk fibers bearing ZnO nanoparticles at 150 °C for 6 h. The obtained ZnO nanostructures were characterized using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), and UV-vis and fluorescence spectroscopic analysis. The size (~500–700 nm) in length and thicknesses (~60 nm) of ZnO nanoflakes were produced. The catalysis performances of ZnO nanoflakes on silk fibers (ZnSk) via photo-degradation of naphthalene (93% in 256 min), as well as Rose Bengal dye removal (~1.7 mM g−1) through adsorption from aqueous solution, were practically observed. Further, ZnSk displayed superb antibacterial activity against the tested model gram-negative Escherichia coli bacterium. The produced ZnSk has huge scope to be used for real-world water contaminants remediation applications.
