Background:Modified electrodes have advanced from the initial studies aimed at understanding electron transfer in films to applications in areas such as energy production and analytical chemistry. This review emphasizes the major classes of modified electrodes with mediators that are being explored for improving analytical methodology. Chemically modified electrodes (CMEs) have been widely used to counter the problems Read More

N,N’-dialkylimidazolium-ion liquids are one of the important ionic liquids with a wide range of applications as a conductive electrolyte and in electrochemistry. The modified electrodes create a new view for the fabrication of electroanalytical sensors. Many modifiers have been suggested for modification of electroanalytical sensors since many years ago. Over these years, ionic liquids and especially room temperature ioni Read More

Background: The rapid and increasing use of the nanomaterials in the development of electrochemiluminescence (ECL) sensors is a significant area of study for its massive potential in the practical application of nanosensor fabrication. Recently, nanomaterials (NMs) have been widely applied in vast majority of ECL studies to remarkably amplify signals owing to their excellent conductivity, large surface area and sometimes catal Read More

Diagnosis of cancer in the early stages can help treat efficiently and reduce cancerrelated death. Cancer biomarkers can respond to the presence of cancer in body fluids before the appearance of any other symptoms of cancer. The integration of nanomaterials into biosensors as electrochemical platforms offer rapid, sensitive detection for cancer biomarkers. The use of surface- modified electrodes by carbon nan Read More

Background: Currently, nanotechnology and nanomaterials are considered as the most popular and outstanding research subjects in scientific fields ranging from environmental studies to drug analysis. Carbon nanomaterials such as carbon nanotubes, graphene, carbon nanofibers etc. and non-carbon nanomaterials such as quantum dots, metal nanoparticles, nanorods etc. are widely used in electrochemical drug analysis for se Read More

Background: Over the past few decades, environmental pollution has appeared to be one of the most crucial global problems. The widespread intensification of numerous hazardous pollutants in the environment needs modern researchers to develop viable, reproducible and costeffective determination tools for reliable environmental analysis. The beneficial, as well as perilous, biological compounds, are receiving growing i Read More

Background:Ceramics can reflect ancient technology and art; therefore, it has a very important position in archaeology. However, it is far from enough just to study the shape of pottery and porcelain. It is necessary to use advanced scientific and technological means to conduct a comprehensive analysis of pottery and porcelain, so as to study the information hidden deep in the remains of ceramic objects. Methods Read More

Background: Catecholamines are a large group of pharmacological and biological compounds that are widely used in biological systems. These compounds are prepared both naturally and synthetically with many key roles in the human body and its activities. Therefore, many researchers focused on the identification and determination of catecholamines in biological samples. Methods: MgO/SWCNTs were synthesized throu Read More

Background:In this research work, a drug sensor (salicylic acid, in this case) was designed . The senor was made by modification of paste electrode (MPE) with CuO-SWCNTs and 1- hexyl-3-methylimidazolium chloride (HMICl). The MPE/CuO-SWCNTs/HMICl showed catalytic activity for the oxidation signal of salicylic acid in phosphate buffer solution Methods:Electrochemical methods were used as a powerful strategy for the determin Read More
