Submit Manuscript | http://medcraveonline.com immense number of publications appeared dealing mainly with the determination of the four “classical” metals easily accessible by inverse voltammetry on mercury electrodes, i.e., Zn, Cd, Pb and Cu. Along with such prosperity in voltammetry also potentiometry slipped into its golden age with the development of new ion selective membranes for many of ...

Inkjet printing is an appealing technique to print electrodes for Dielectric Elastomer Actuators (DEAs). Here we present the preparation and ink-jet printing of a carbon black electrode mixture and characterise its properties. Carbon black has been used extensively in the past because it is very compliant; however, it has a high resistance and can be very dirty to work with. In this paper we sh...

A novel and highly sensitive electrochemical method for the detection of pyritinol in pharmaceutical products and serum samples has been accomplished based on voltamperometric response of pyritinol in carbon nanofiber-gold nanoparticle (CNF-GNP)-modified screen-printed carbon electrode (SPCE). The electrochemical response of pyritinol to CNF-GNP-modified SPCE was studied by cyclic voltammetry a...

In this paper in situ bismuth, antimony, tin modified electrodes and combinations thereof are explored towards the model target analytes cadmium(II) and lead(II), chosen since they are the most widely studied, to explore the role of the underlying electrode substrate with respect to boron-doped diamond, glassy carbon, and screen-printed graphite electrodes. It is found that differing electroche...

Screen-printed carbon electrode (SPCE) is one of the most interesting designs to combine a working (from based material), reference, and counter in single-printed substrate. SPCE has been used many electrochemical measurements due its advantages for analysis microscale. This paper summarises main information about fabrication from material technique aspect on flat substrate work that published ...

A simple procedure for the voltammetric detection of antioxidative activity of plant extracts based on the protection from DNA damage at the electrode surface is reported. A disposable electrochemical DNA biosensor fabricated as a carbon-based screen-printed electrode modified by a surface layer of the calf thymus double stranded (ds) DNA was used as a working electrode in combination with a si...

Fabrication and electrochemical characterization of disposable working electrodes/transducers of electrochemical sensors is described in this work. The aim was to find the best electrochemical properties of screen-printed electrode substrates modified with multiwalled carbon nanotubes (MWCNTs) based active layers. Two types of platinum electrode contacts were investigated and the suitable thick...

A separation-free electrochemical immunoassay method for the detection of the pesticide atrazine is described. The method developed is a competitive ELISA incorporating disposable screen printed horseradish peroxidase modified electrodes as the detector element in conjunction with single-use atrazine immuno-membranes. Screen printed carbon electrodes were prepared using carbon ink incorporating...
