Magnetic core-shell [Fe.sub.3][O.sub.4] at the rate of Ag nanoparticles coated carbon paste interface for studies of carcinoembryonic antigen in clinical immunoassay
Article Abstract:
A new approach toward development of advanced immunosensors based on chemically functionalized core-shell [Fe.sub.3][O.sub.4] at the rate of Ag magnetic nanoparticles is described with the preparation, characterization, and measurement of relevant properties of the immunosensor useful for the detection of carcinoembryonic antigen (CEA) in clinical immunoassay. The immobilized anti-CEA molecules show an excellent electrochemical response selective to the CEA and the core-shell nanostructure presents good magnetic properties to facilitate and modulate the way it was integrated into a carbon paste.

Enhancing and quenching functions of silver nanoparticles on the luminescent properties of Europium complex in the solution phase
Article Abstract:
Luminescent properties of the Eu(dinic) complex, where dinic is dinicotinic acid, were examined in the presence of silver nanoparticles in N,N-dimethylformamide. The formation of particle aggregates was observed upon mixing the particle solution with the complex solution, in which the complexes behaved like linker molecules.

Molecular number in core and shell: Structural dependence of reactivity of alkylcarboxylate-stabilized silver nanoparticles
Article Abstract:
Spectroscopic, chemical, thermal and voltammetric analyses on six kinds of alkylcarboxylate-stabilized silver nanoparticles 4.7 nm in diameter were carried out. The analysis reveals the effect of alkylcarboxylates on the optical, thermal, geometric and electrochemical properties of the nanoparticles.
