Sequential injection system (SI system) was used for the pretreatment of a carbon electrode in an anodic stripping voltammetry (ASV) for the determination of arsenic (III). In this research, a screen-printed carbon electrode (SPCE) was used; SPCE was prepared in our laboratory by us. In ASV, SPCE was chosen as a working electrode because SPCE is less expensive, easy to use for a flow cell and s...

The first electrochemical immunosensor (EI) for the detection of antibodies against deamidated gliadin peptides (DGP) is described here. A disposable nanohybrid screen-printed carbon electrode modified with DGP was employed as the transducer's sensing surface. Real serum samples were successfully assayed and the results were corroborated with an ELISA kit. The presented EI is a promising analyt...

We report here the development of a novel disposable-type glucose enzyme sensor based on a screen-printed carbon electrode (SPCE) employing a catalytic subunit of FAD-dependent glucose dehydrogenase (FADGDH) and a Rucomplex (hexaammineruthenium (III) chloride) as the electron mediator. The whole blood glucose measurement was achieved in 2 seconds using a 500 nl sample of the range of 100-800 mg...

A novel multi-channel electrode array sensing device was fabricated by screen-printing techniques using 96-well plate as the template. To confirm its practical value, we developed a one-step preparation of multi-walled carbon nanotubes (MWCNTs) doped electrode array by an ink containing MWCNTs, which was applied to the simultaneous detection of a variety of biological samples and environmental ...

In this study, for the first time, a simple immunosensor for ultrasensitive recognition of Human Chorionic Gonadotropin (hCG) in serum samples was fabricated by exploiting a simple approach. In this method, a low-cost and sensitive immunosensor was fabricated based on QDs-N-S/Au nanoparticles (NPs) modified Screen-Printed Carbon Electrode (SPCE). It seems that, QDs-N-S/Au NPs/ antibody as a bio...

In this study, we developed a simple high-throughput and cost-effective method for monitoring toxic metal ion in an environmental aqueous sample. Mercury determination with Sequential Injection Analysis system (SIAs) coupled the electrochemical detection on modified screen-printed carbon working electrode (SPCE) is alternative green analysis of mercury ion. The gold film was used as material im...
