Green synthesis of Conductive Porous Film and its Application on Screen-Printed Electrodes Used For Biomedical Application

Currently, most researchers are choosing screen-printed electrodes (SPEs) as detectors in developing biosensors. The production of these SPEs entails thin film deposition, which entails the application of nanomaterials and binders onto diverse, flexible substrates like plastic, paper, or textiles. Nanomaterials, such as nanoparticles (NPs), nanofibers, and nanowires, improve the performance of these biosensors. Moreover, their large surface areas make them valuable for achieving enhanced biomolecule immobilization. Nanomaterial-based SPEs facilitate rapid, effortless, cost-effective on-site analysis that is exceedingly precise, replicable, and responsive. Conventional nanomaterial production methods, such as physical and chemical processes, pose hazards to human health and the environment due to harmful ingredients and unsafe reaction circumstances. A practical approach to addressing this problem is organic synthesis, called "green synthesis." Green synthesis is founded on creating and employing methods that reduce or eliminate the use of hazardous substances and waste. This article introduces an innovative method for creating a conductive porous film (CPF) using natural materials. The film created is also applied to a flexible paper-based SPE, and its electrical properties were analyzed.
