Herein, we report a polyamine-mediated assembly to integrate graphene oxide (GO) sheets with Ag/AgCl to fabricate a hybrid nanocomposite (GO-Ag/AgCl) at nearly neutral pH and ambient temperature. Inspired by the role of polyamines in the excellent integration of components to generate hierarchical nanostructures in biominerals such as diatoms, we showed that our strategy enabled the fabrication...

A universal chitosan-assisted method was developed to synthesize various Ag-including heterostructured nanocrystals, in which chelation probably plays a vital role. The as-prepared Ag/Pd heterostructured nanocrystals show outstanding properties when used as bifunctional nanocomposites in label-free in situ SERS monitoring of Pd-catalyzed reaction.

The determination of cholesterol is increasingly important for the fact that high serum cholesterol level was related with many diseases. In this work, a new cholesterol biosensor was developed based on the gold-graphene nanocomposite material prepared by one-step electrodeposition. The nanomaterial formed on a glassy carbon electrode was proved by scanning electron microscope and the electroch...

In this work, a novel amperometric immunosensor based on multi-walled carbon nanotubes-thionine-chitosan (MWCNTs-THI-CHIT) nanocomposite film as electrode modified material was developed for the detection of chlorpyrifos residues. The nanocomposite film was dropped onto a glassy carbon electrode (GCE), and then the anti-chlorpyrifos monoclonal antibody was covalently immobilized onto the surfac...

The controlled wettability of gold nanocomposite surfaces obtained by laser irradiation is introduced. Starting from the conception of materials with controlled surface properties, we describe all the different steps to generate the gold functionalized nanocomposite material and illustrate its surface wettability. Photopatterned gold polymeric films are performed in order to exhibit a remarkabl...

In this study, nanometer sized of Ag/Fe3O4 nanocomposite (AFN) have been synthesized by using a simple and based on chemical reduction method. The size and shape of (AFN) controlled by using of condensation (Fe2O3 (2.975 mmol), NaBH4 (21.25 mmol), AgNO3 (2.532 mmol) and polyvinylpyrrolidone (PVP) (8.925 mmol K30 Mr=10.000) in 40 ºC. The synthesized AFN was characterized by XRD, scanning electro...

Ag loaded metal tungstate-organic framework-based nanocomposite (g-C3N4/Ag/ZnWO4), which generates greater number of oxygen defects plays crucial role in the selective detection toxic ions solution.

In this research work, electrochemical biosensor was fabricated based on immobilization of tyrosinase onto graphene-decorated gold nanoparticle/chitosan (Gr-Au-Chit/Tyr) nanocomposite-modified screen-printed carbon electrode (SPCE) for the detection of phenolic compounds. The nanocomposite film was constructed via solution casting method. The electrocatalytic activity of the proposed biosensor ...

We report on the observation of the helicity-dependent photoresponse of the 20-μm-thick silver-palladium (Ag/Pd) nanocomposite films. In the experiment, 120 fs pulses of Ti:S laser induced in the film an electric current perpendicular to the incidence plane. The photoinduced current is a linear function of the incident beam power, and its sign depends on the beam polarization and angle of incid...
