Cu/carbon Paste Electrodes for Insulin Detection
Abstract
Electrochemical detection of insulin in body fluids is considered to be novel approach for diabetes diagnosis. In this study, environmentally friendly carbon paste electrode was constructed. The electrode was prepared from the waste processed material, coconut oil and pencil. Electrochemical properties of prepared electrode material was studied and ideal composition of paste was considered. The paste electrode was modified by Cu material, via cyclic voltammetry to ensure selective interaction with insulin, due to Cu-insulin complex formation. The proposed carbon material displays linear range within 1 to 4 µM and sensitivity 0.45 mM/µM. The proposed results displays promise for future usage in the real samples detection.
Short Biography
Dr. Ivana Šišoláková has been an University Associate Professor and Head of the Department of Physical Chemistry at the Faculty of Science, Pavol Jozef Šafárik University in Košice since 2022. Her research is focused on the development of novel electrochemical sensors for biomedical applications, particularly in disease diagnostics. For several years, she has been working on the design of non-enzymatic electrochemical sensors for insulin detection, offering a promising new approach to early-stage diabetes diagnosis. After the outbreak of the COVID-19 pandemic in 2020, her research shifted toward the development of electrochemical biosensors for the rapid and selective detection of viral pathogens, especially SARS-CoV-2. She is the author and co-author of numerous scientific publications indexed in international databases (Web of Science and Scopus) and actively participates in national and international research projects.
