Laser-induced graphitization leads to screen printed highly oriented pyrolytic graphite electrodes.

The fabrication, evaluation and attractive performance of multiwall carbon nanotube(MWCNT)/polysulfone biocomposite membrane modified thick-film screen-printed electrochemical biosensors are reported. The fabricated carbon nanotube/polysulfone (CNT/PS) strips combine the attractive advantages of carbon nanotube materials, polysulfone matrix and disposable screen-printed electrodes. Such thick-f...

This paper presents a sensitive simultaneous detection procedure for Sudan I and bisphenol A based on the multiwalled carbon nanotubes (MWCNTs)/Co3O4 nanocomposite modified screen-printed graphite electrode (SPGE). MWCNTs/Co3O4 was prepared by hydrothermal technique, characterized Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM) X-ray diffrac...

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 biosensor was developed by immobilizing laccase onto mercury thin film electrode (MTFE) by means of gelatin that is then crosslinked with glutaraldehyde. Mercury thin film (MTF) was deposited onto glassy carbon electrode (GCE) and the obtained biosensor was utilized for the determination of phenolic compounds. The measurement was based on the amperometric detection of oxygen consumption in re...

A biosensor for the detection of triazine- and phenylurea-type herbicides was constructed using isolated Photosystem II (PS II) complexes as a biosensing element. PSII isolated from the thermophilic cyanobacterium Synechococcus elongatus was immobilized on the surface of a screen-printed sensor composed of a graphite working electrode and Ag/AgCl reference electrode deposited on a polymeric sub...

This work presents the development and validation of an electroanalytical method for Pb(II) determination in a single drop. The electrochemical sensors used were unmodified screen-printed electrode (SPE) Bi-film SPE (BiFSPE). Anodic square wave stripping voltammetry (SWASV) was performed at accumulation potential −1.5 V vs. Ag/AgCl time 60 s. Electroanalysis with did not yield satisfactory resu...
