Despite noteworthy progress in the fabrication of large-area graphene sheetlike nanomaterials, vapor-based processing still requires sophisticated equipment and a multistage handling material. An alternative approach to manufacturing functional graphene-based films includes employment oxide (GO) micrometer-scale sheets as precursors. However, search for scalable technique production high-quality GO nanoscale with high uniformity electrical conductivity is continuing. Here we show that...
With the advancement of nanotoxicology and nanomedicine, it has been realized that nanoparticles (NPs) interact readily with biomolecular species other chemical organic matter to result in biocorona formation. The field environmental health safety nanotechnology, or NanoEHS, is currently lacking significant molecular-resolution data, we set out characterize formation through electron microscopy imaging circular dichroism spectroscopy inspired a novel approach for molecular dynamics (MD)...
A novel triple helix based on proton-transferred sebacic acid was observed in a 1:1 organic salt of [(Hambtz)+(Hsba)−·2H2O] (1, ambtz = 2-amino-6-methoxybenzothiazole, H2sba acid) incorporating zigzag water chain. Changing the solvent system, another simple 1D chain, cocrystal [(ambtz)2(H2sba)] (2), obtained. The structural dissimilarity between them dependent different conformations and modulated by systems. photoluminescence behaviors 1 2 were also discussed.
We have characterized the binding of cytoskeletal proteins, namely, tubulin and actin, with silver nanoparticles using techniques dynamic light scattering, UV-Vis spectrophotometry, circular dichroism spectroscopy, hyperspectral imaging, transmission electron microscopy. Overall, actin displayed a higher propensity than for while both proteins experienced conformational changes upon binding. Conversely, ion release from was significantly compromised formation protein biocoronas, as shown by...
We describe a simple technique to alter the shape of silver nanoparticles (AgNPs) by rolling glass tube over them mechanically compress them. The resulting change in turn induces red-shift localized surface plasmon resonance scattering spectrum and exposes new area. flattened particles were characterized optical electron microscopy, single-nanoparticle spectroscopy, surface-enhanced Raman spectroscopy (SERS). Atomic force microscopy scanning images show that AgNPs deform into discs;...
