1Solid-state electrochemiluminescence protein biosensor with aptamer substitution strategy显示文摘One solid-state electrochemiluminescence(ECL) protein biosensor based on the competing reaction and substitute reaction between protein-to-DNA aptamer and DNA-to-DNA aptamer was proposed.Additionally,the biosensor was based on ECL photo-quenching effect of ferrocene(Fc) to tris(2,2'-bipyridyl)ruthenium(II)(Ru(bpy)32+).It was built up by modification of Au nanoparticles(AuNPs) and Ru(bpy)3 2+ on one Au electrode firstly,and then self-assembly of one special double-stranded DNA(dsDNA) onto the electrode.This dsDNA was prepared by hybridization of one Fc labeled molecular beacon single-stranded DNA(ssDNA) and one anti-thrombin aptamer ssDNA.Without the target protein,this Fc-dsDNA/Ru(bpy)3 2+-AuNPs/Au electrode trigged strong ECL signal,so we called it ECL 'signal on' state.When thrombin was present in the sensing solution,the protein reacted with its aptamer from the Fc-dsDNA/Ru(bpy)3 2+-AuNPs/Au electrode.Then the left molecular beacon ssDNA on the electrode recovered to its normal stem-loop structure and consequently its Fc labeler was close enough to the electrode surface to quench the ECL signal from Ru(bpy)3 2+.It was in ECL 'signal off' state.We measured the decrease in ECL intensity to sense the target protein.This was one endeavour to sense protein by using un-labeling target or probe strategy,which gave higher sensitivity and selectivity due to the better combination efficiency of protein and the un-labeled aptamer.6.25 fmol/L thrombin was detected out.XU Ying DONG Ping ZHANG XiaoYan HE PinGang FANG YuZhi 2011Science China Chemistry2011,54,7:2

3Configuration and capacitance properties of polypyrrole/aligned carbon nanotubes synthesized by electropolymerization显示文摘Aligned carbon nanombes(ACNTs) were modified with polypyrrole(PPy) via electropolymerization.Because of the large specific surface area and excellent electrical conductivity of ACNTs,continuous electropolymerization was able to be carried out,forming a thick PPy coating on the ACNTs.The resulting nanocomposite possessed a core-shell structure with ACNTs as the core PPy as the shell,and nanoparticles of PPy on the top,and displayed high performance supercapacitance properties.XU Ying ZHUANG ShuQi ZHANG XiaoYan HE PinGang FANG YuZhi 2011Chinese Science Bulletin2011,56,35:1
