Hybrid (organic shell-inorganic core) nanoparticles have important applications in nanomedicine. Although the inorganic components of hybrid nanoparticles can be characterized readily using conventional transmission electron microscopy (TEM) techniques, the structural and chemical arrangement of the organic molecular components remains largely unknown. Here, we apply TEM to the physico-chemical...

In this study, the immobilization of xylanase using a protein-inorganic hybrid nanoflower system, was assessed to improve the enzyme properties. The synthesis of hybrid xylanase nanoflowers was very effective at 4°C for 72 h, using 0.25 mg/mL protein, and efficient immobilization of xylanase was observed with a maximum encapsulation yield and relative activity of 78.5% and 148%, respectively. I...

Impressive performance of hybrid perovskite solar cells reported in recent years still awaits a comprehensive understanding of its microscopic origins. In this work, the intrinsic Hall mobility and photocarrier recombination coefficient are directly measured in these materials in steady-state transport studies. The results show that electron-hole recombination and carrier trapping rates in hybr...

Transparent Nonlinear Optical (NLO) inorganic/organic (polyimide/silica) hybrid composites with covalent links between the inorganic and the organic networks were prepared by the sol-gel method. The silica content in the hybrid films was varied from 0 to 22.5/wt%. The prepared PI hybrids were characterized by IR, UV-Vis, Thermogravimetric analysis (TGA), X-ray diffraction (XRD), Scanning Electr...

Surfactants are molecules of enormous scientific and technological importance, which are widely used as detergents, emulsifiers, and for the preparation of diverse nanostructures. Their fascinating ability to form self-organized structures, such as micelles or liquid crystals, originate from their amphiphilic architecture-a polar head group linked to a hydrophobic chain. While almost all known ...

Nanotechnology offers immense opportunities for regulating and improving biological functions of proteins in vitro. Recent years have witnessed growing efforts to develop protein-incorporated hybrid nanostructured materials with potential applications in functional materials, enzymatic catalysis, drug delivery, and analytical sciences. In this review, recent advances in functional protein-organ...

Responsive polymeric assemblies and hybrid superstructures fabricated from stimuli-sensitive polymers and inorganic nanoparticles (NPs) have been the subject of extensive investigations during the past few decades due to their distinct advantages such as an improved water solubility, stimuli-responsiveness, excellent biocompatibility, and facile introduction of functional units. In addition, th...

The shell cross-linked (SCL) thermoresponsive hybrid poly(N-isopropylacrylamide-co-aminoethyl methacrylate)b-polymethyl methacrylate (P(NIPAAm-co-AMA)-bPMMA) micelle consisting of a cross-linked thermoresponsive hybrid shell and a hydrophobic core domain was fabricated via a two-step process: micellisation of P(NIPAAm-co-AMA)-b-PMMA in aqueous solution followed by cross-linking of the hydrophil...
