Polymeric Materials for Printed-Based Electroanalytical (Bio)Applications

Abstract

Advances in design of selective interfaces and printed technology have mighty contributed to the expansion of the electroanalysis fame. The real advantage in electroanalytical field is the possibility to manufacture and customize plenty of different sensing platforms, thus avoiding expensive equipment, hiring skilled personnel, and expending economic effort. Growing developments in polymer science have led to further improvements in electroanalytical methods such as sensitivity, selectivity, reproducibility, and accuracy. This review provides an overview of the technical procedures that are used in order to establish polymer effectiveness in printed-based electroanalytical methods. Particular emphasis is placed on the development of electronalytical sensors and biosensors, which highlights the diverse role of the polymeric materials depending on their specific application. A wide overview is provided, taking into account the most significant findings that have been reported from 2010 to 2017.

Office Paper-Based Electrochemical Strips for Organophosphorus Pesticide Monitoring in Agricultural Soil

“…The printed strips have been successively modified with the use of drop casting methodology. 34 A mixture composed of CB, Prussian blue (PB), and BChE has been drop-cast on top of the working electrode. The detailed concentrations are reported in the Experimental Section.…”

Review—An Overview on Recent Progress in Screen-Printed Electroanalytical (Bio)Sensors

“…Additionally, CP nanoparticles offer intrinsic benefits like as ease of surface modification, biocompatibility, and wide surface areas, making them great candidates for application in electrical and optoelectronic sensing devices. 45,46 Electrically conducting polymers are well-known for a variety of properties that make them ideal for immobilizing biomolecules and facilitating electron transfer in the fabrication of effective biosensors. With the use of a macroporous gold screen-printed electrode, Tabrizi and colleagues developed an ultrasensitive molecularly imprinted polymer-based electrochemical sensor for the detection of SARS-CoV-2 RBD.…”

Screen-Printed Voltammetric Sensors—Tools for Environmental Water Monitoring of Painkillers

“…The most frequently used polymers for this purpose are conductive polymers that combine conventional properties of polymers with the electronic properties of metals and/or semiconductors. Mainly polyacetylene, polyaniline, polypyrrole, or polythiophene are used here [ 136 , 137 ]. In addition, it was found that the use of a conductive polymer to modify the electrode surface increases the electrical conductivity, high chemical stability, good magnetic properties, high electron affinity, optical properties, and low ionization potential [ 138 ].…”
