Abstract
Field effect transistors (FETs), originally developed in the field of electronic engineering, have gained increasing prominence in biosensing due to their versatile operation characteristics, ranging from recording simple electrical transfer curves to performing chronoamperometric measurements. Commonly known as bioFETs, these devices typically feature low gate voltage operation characteristics, can be made highly selective/sensitive through bioreceptor integration, label-free and do not rely on redox mediators or enzymatic product detection, and are easy to interface with microfluidic or flow cell devices. Despite their advantages, electrochemists and biologists remain still hesitant to explore the possibilities of bioFETs, owing to concerns about investment costs and the complexity of the read-out tools. In this study, we demonstrate the use of a simple, cost-effective bipotentiostat platform, providing an accessible solution for those interested in electronic biosensing without the need to delve into complex electronics. As a proof-of-concept, we showcase the working principle of a graphene-based bioFET for sensing a cardiac biomarker using a peptide nucleic acid (PNA)-aptamer-modified gFET platform. This article focuses on how to easily develop/operate FETs for biosensing measurements using the bipotentiostat-setup and discloses its simplicity over the conventional approaches.
期刊介绍:
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
