In this work, glassy carbon paste electrode (GCPE) was modified with banana tissue and nanomaterials like gold nanoparticles (Au-nps) and HNO(3) treated multi-walled carbon nanotubes (MWCNTs). As a result three types of ...

We report on the determination of choline and acetylcholine via biocentrivoltammetry. This method combines centrifugation and voltammetry and is based on a carbon paste electrode modified with acetylcholinesterase and ...

Mushroom tissue was immobilized onto plain screen printed electrode (SPE) and multiwalled carbon nanotube (MWCNT) modified SPE (SPE/MWCNT) via bismuth (Bi) deposition. By this way. SPE/Bi/Tissue and SPE/MWCNT/Bi/Tissue ...

Centri-voltammetry is a method that combines centrifugation and voltammetry. This method, developed by our group in 2003, yielded promising results when applied to trace analysis of metal ios. We demonstrate here the first ...

In this study, a bismuth film was used as a sensing platform for immunoreaction assay which includes the interactions between IgE and anti-IgE molecules. For preparing this assay, IgE was deposited on a carbon paste electrode ...

A biosensor for monitoring alkaline phosphatase (ALP) enzyme activity was developed by using bismuth film electrode (BiFE) as transducer. The aim was to test the possible applications of BiFE as transducer in this biosensing ...

The electroanalytic performances of glassy carbon paste electrode (GCPE), multi-walled carbon nanotube (MWCNT)-GCPE and double-walled carbon nanotube (DWCNT)-GCPE, which include HNO3 washed/unwashed materials, were compared ...

In this study, manganese(IV) oxide (MnO2) nanoparticle (np)-modified glassy carbon paste electrode is used for ascorbic acid (AA) detection in fruit juice samples. The experimental parameters like MnO2 np amount and pH ...
