Phosphate concentration is an important indicator of water quality, specifically for eutrophication levels in the presence of algae. Several analytical techniques have been proposed for phosphate monitoring, and most of them are based on indirect methods. In this study, we propose a new reagent-less direct method for the electrochemical detection o...
We have recently reported laser-induced fibers (LIF) as a promising nanomaterial that possesses good electrochemical activity and are easily manufacturable. In this paper, for the first time, the application of LIF as functionalization materials on laser-induced graphene (LIG) electrodes for the detection of nitrate is demonstrated. The as-fabricat...
This paper proposes biosensors designed specifically for dielectric spectroscopy on biological cells while they are in their liquid culture medium, covering the microwave frequency spectrum from 10 GHz to 50 GHz. This frequency range is suitable for measurements with very low concentrations of cells. The biosensors are designed by integrating an in...
Impedance spectroscopy is a powerful measurement method having decisive advantages in several application fields. It allows the measurements of non-accessible quantities, supports high measurement accuracy, and enables simultaneous measurements of more than one quantity. The method provides deep insights into systems and materials, is non-invasive,...

Excessive nitrite amounts harm the environment and put public health at high risk. Therefore, accurate and sensitive detection of nitrite in surface and groundwater is mandatory for mitigating its adverse effects. Herein, a highly sensitive electrochemical sensor based on carbon screen-printed electrodes (CSPE) surface-modified with photochemically...
Cover Story: Electrochemical sensors are sensitive, portable, fast, inexpensive, and suitable for online and in situ measurements compared to other methods. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other e...
Electrochemical sensors play a significant role in detecting chemical ions, molecules, and pathogens in water and other applications. These sensors are sensitive, portable, fast, inexpensive, and suitable for online and in-situ measurements compared to other methods. They can provide the detection for any compound that can undergo certain transform...
This paper aims to develop a novel electrochemical sensor for nitrite (NO2-) detection as it is harmful to public health and environment beyond safe limits. The electrochemical sensor is based on graphite
screen printed electrodes (GSPE) modified with nontoxic and biocompatible gold nanoparticles stabilized by branched polyethyleneimine (AuNPs-PEI)...
Questions
Question (1)
While testing my target X, it has an oxidation potential at 0.5V. For the interference test, a mixture of my target X and an interfering ion Y was done. While running CV or DPV the oxidation potential has shifted. How to explain that?
Also, what does mean if I get a large oxidation peak instead of a sharp one?
Thank you!
