DNA nanostructures are finding diverse applications as scaffolds for molecular organization. In general, components such as nucleic acids, proteins, and nanoparticles are attached to addressable DNA nanostructures via hybridization, and there is interest in exploiting hybridization for localized computation on DNA nanostructures. This report details two fluorescence microscopy methods, single-p...

zno nanorods and nanoparticles have been easily prepared via the decomposition of two simple schiff base zinc (ii) complexes, namely (n,n'–disalicylalethylenediamine)zince(ii) and (n,n'–disalicylalphenylenediamine)zince(ii) under microwave irradiation. the decomposition products of the complexes were characterized by ft-ir, xrd, sem, edx and uv-visible spectroscopy.  ft-ir, xrd and edx results ...

Strong chiroptical effects recently reported result from the interaction of light with chiral plasmonic nanostructures. Such nanostructures can be used to enhance the chiroptical response of chiral molecules and could also significantly increase the enantiomeric excess of direct asymmetric synthesis and catalysis. Moreover, in optical metamaterials, chirality leads to negative refractive index ...

Ag nanostructures are widely used in catalysis, energy conversion and chemical sensing. Morphology-tailored synthesis of Ag nanostructures is critical to tune physical and chemical properties. In this study, we develop a method for synthesizing the morphology-tailored Ag nanostructures in aqueous solution at a low temperature (45 °C). With the use of AgCl nanoparticles as the precursor, the gro...

Water-soluble Ag-Au bimetallic nanostructures were prepared via co-reduction and seed-mediated growth routes employing poly-(4-styrenesulfonic acid-co-maleic acid) (PSSMA) as both a reductant and a stabilizer. Ag-Au alloy nanoparticles were obtained by the co-reduction of AgNO3 and HAuCl4, while Ag-Au core-shell nanostructures were prepared through seed-mediated growth using PSSMA-Au nanopartic...

Objective (s): SrCO3 nanoparticles could be used as new biomedical sources in magnetic resonance imaging as a promising noninvasive imaging modality for the preoperative staging of breast cancer and monitoring of tumor response to therapy. The present study aimed to synthesize SrCO3 nanostructures using microwave irradiation in the presence of honey as a green capping agent and reductant. Mater...

bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. thioglycolic acid is used as sulfur source and capping agent simultaneously. bi2s3 nanostructures were then added to acrylonitrile-butadiene-styrene (abs) copolymer. the thermal stability behavior of abs filled with bismuth sulfide nano-rods were investigated by thermogravime...

The non-iridescent structural colours of avian feather barbs are produced by coherent light scattering from amorphous (i.e. quasi-ordered) nanostructures of b-keratin and air in the medullary cells of feather barb rami. Known barb nanostructures belong to two distinct morphological classes. ‘Channel’ nanostructures consist of b-keratin bars and air channels of elongate, tortuous and twisting fo...

Nickel oxide nanostructures with different lengths have been easily synthesized by calcining nickel foil after soaking in LiOH solution of different concentrations. The measurements of electrochemical properties of these NiO nanostructures show that different lengths of NiO nanostructures would have different electrochemical properties and the NiO nanowires with the longest length have the larg...
