ArticleCarbon Black-Modified Electrodes Screen-Printed onto Paper Towel
Herein, we evaluated the use of paper towel, waxed paper, and Parafilm M® (Heathrow Scientific, Vernon Hills, IL, USA) as alternative substrates for screen-printed sensor manufacturing. Morphological study was performed to evaluate the adhesion of the ink on these uncommon substrates, as well as the morphology of the working electrode. The electrochemical characterization was carried out using ...

متن کاملEffect of pre-treatment on the surface and electrochemical properties of screen-printed carbon paste electrodes.
The effect of various electrochemical pre-treatment methods on the surface and electrochemical properties of screen-printed carbon paste electrodes (SPCE) prepared with three different commercial products was examined. It was observed that a positively charged redox couple, e.g., hexaammineruthenium(III), exhibited quasi-reversible behavior at the untreated SPCE. However, the cyclic voltammogra...
متن کاملScreen Printed Electrodes Used for Detection of Ionic Heavy Metals
Electrochemical sensors and biosensors based on inhibition are sensitive methods to determine the concentration of toxic substances in environment and clinic applications. Heavy metal cations bind to biological molecules and inactive important enzyme systems, such as acetylcholinesterase (AChE). In this paper, the amperometric sensors and biosensors based on AChE inhibition were developed using...
متن کاملLabel-free impedimetric aptasensor for lysozyme detection based on carbon nanotube-modified screen-printed electrodes.
We report on the direct electrochemical detection of aptamer-protein interactions, namely between a DNA aptamer and lysozyme (LYS) based on electrochemical impedance spectroscopy (EIS) technique. First, the affinity of the aptamer to LYS and control proteins was presented by using filter retention assay. An amino-modified version of the DNA aptamer-recognizing lysozyme was covalently immobilize...
