The crystal structure of a novel hypothetical protein, KD93, expressed in human hematopoietic stem/progenitor cells, was determined at 1.9A resolution using the multiple-wavelength anomalous dispersion (MAD) method. The protein KD93, which is encoded by the open reading frame HSPC031, is a NIP7 homologue and belongs to the UPF0113 family. The structural and(More)
In this report, N, S-codoped fluorescent carbon nanodots (NSCDs) were prepared by a facile, simple, low-cost, and green thermal treatment of ammonium persulfate, glucose, and ethylenediamine. The as-prepared NSCDs displayed bright blue emission with a relatively high fluorescent quantum yield of 21.6%, good water solubility, uniform morphology, and(More)
The purpose of this study was to evaluate the effect of carbon dioxide laser irradiation on the performance of silane coupling agent as an adhesion promoter. The carbon dioxide laser used in this study was Opelaser 03S II, which irradiated the silane coupling agent applied on the adhesive surface of porcelain. Before and after thermal cycling, shear bond(More)
The aim of this study was to develop a rapid method to measure alpha-fetoprotein (AFP) in human serum by use of one-step sandwich enzyme-linked immunosorbent assay (ELISA)-based immunobiosensor with disposable screen-printed carbon electrode technology. Prussian blue (PB) was deposited using cyclic voltammetry (CV) on the surface of electrode to catalyze(More)
Monodisperse Fe3O4 magnetic nanoparticles (NPs) were prepared under facile solvothermal conditions and successively functionalized with silica and Au to form core/shell Fe3O4@silica@Au NPs. Furthermore, the samples were used as matrix to construct a glucose sensor based on glucose oxidase (GOD). The immobilized GOD retained its bioactivity with high protein(More)
A simple, facile and green hydrothermal method was developed in the synthesis of water-soluble nitrogen-doped carbon dots (N-CDs) from streptomycin. The as-prepared N-CDs displayed bright blue fluorescence under the irradiation of UV light, together with a high quantum yield of 7.6% and good biocompatibility as demonstrated by the cell viability assay.(More)
Developing new nanomaterials is of key importance to improve the analytical performances of electrochemical biosensors. In this work, palladium-copper alloyed nanocages supported on reduced graphene oxide (RGO-PdCu NCs) were facilely prepared by a simple one-pot solvothermal method. A novel phenol biosensor based on laccase has been constructed for rapid(More)
Porous bimetallic alloyed palladium silver (PdAg) nanoflowers supported on reduced graphene oxide (PdAg NFs/rGO) were prepared via a facile and simple in situ reduction process, with the assistance of cetyltrimethylammonium bromide as a structure directing agent. The as-prepared nanocomposite modified glassy carbon electrode (PdAg NFs/rGO/GCE) showed(More)
In this work, a facile one-pot wet-chemical method was developed for the self-assembly of PdPt@Pt nanorings via in situ reduction of [PdCl4](2-) and [PtCl6](2-) at room temperature, which are simultaneously dispersed on reduced graphene oxide (rGO; denoted as PdPt@Pt/rGO). Hexadecylpyridinium chloride was demonstrated as a shape-directing agent and formic(More)
Herein, a single-step co-reduction aqueous route was designed for preparation of hierarchical AuPt alloy nanochains, firstly using amprolium hydrochloride as a new stabilizing agent and structure-director. The morphology, structure, composition, and size of the products were characterized by a series of technique. The growth mechanism of AuPt nanochains was(More)
