In this work, a sensitive electrochemiluminescence (ECL) sensor for the determination of melamine (MEL) was developed based on a Ru(bpy)32+-doped silica nanoparticles (RUDS)/carboxylic acid functionalized multi-walled carbon nanotubes (CMWCNTs)/Nafion composite film modified electrode. The homogeneous spherical RUDS were synthesized by a reverse microemulsion method. As Ru(bpy)32+ were encapsulated...
A new method of capillary electrophoresis (CE) coupled with tris(2, 2′-bipyridyl) ruthenium(II) electrochemiluminescence (ECL) detection has been developed to detect four local anesthetics procainamide (PAH), tetracaine (TCH), proparacaine (PCH) and cinchocaine (CIN) simultaneously. An europium (III)-doped prussian blue analogue film (Eu-PB) modified platinum electrode was prepared and applied to...
A highly sensitive electrogenerated chemiluminescence (ECL) biosensor was developed on the basis of a closed bipolar electrode (BPE) apparatus for the analysis of prostate specific antigen (PSA). Bipolar modifications bring up two different stages of enhancement on the same electrode. Anodic enhancement was conducted by modifying gold nanoparticles (Au NPs) to catalyze the anodic ECL reaction between...
Sensitive and selective determining bio-related molecule and enzyme play an important role in designing novel procedure for biological sensing and clinical diagnosis. Herein, we found that dual-stabilizers-capped CdSe quantum dots (QDs) in composite film of multi-walled carbon nanotubes (CNTs) and Nafion, displaying eye-visible monochromatic electrochemiluminescence (ECL) with fwhm of 37nm, which...
A novel and highly sensitive electrochemiluminescence (ECL) biosensing system was designed and developed for individual detection of different organophosphorous pesticides (OPs) in food samples. Bimetallic Pt-Au nanoparticles were electrodeposited on multi-walled carbon nanotubes (MWNTs)-modified glass carbon electrode (GCE) to increase the surface area of electrode and ECL signals of luminol. Biocomposites...
Here, we propose a simple and novel “signal-on” electrochemiluminescence (ECL) biosensor based on resonance energy transfer (RET) for detection of prostate specific antigen (PSA). The system is composed of Multi-walled carbon nanotubes (MWCNT), polyamidoamine (PAMAM) dendrimer and Au nanoparticles (NPs) film on glassy carbon electrode (GCE) to improve the electron transfer, provide abundant amine...
