A review on synthesis and applications of polyaniline and polypyrrole hydrogels

Bioactivation of Polyaniline for Biomedical Applications and Metal Oxide Composites

“…e biocompatibility, biodegradability, and antiproliferative power of the polyaniline against pathogenic bacteria, as well as its conjugation capacity with biologically active molecules, have led to its use in enzymatic biosensors for triglyceride detection, support for enzyme immobilization, controlled drug release systems, tissue engineering, arti cial muscles, and nerve growth and regeneration [3][4][5]. e reversible volumetric changes that polyaniline undergoes under controlled electrical pulses, on the other hand, have been used in the fabrication of actuators, as well as other biomedical applications [3][4][5][6]. A gel is a three-dimensional network of exible chains made up of segments that are connected in a speci c pattern and swollen by a liquid.…”

A short review on the synthesis and advance applications of polyaniline hydrogels

“…The electrochemical properties of PANI hydrogels were mentioned in roughly 33% of the articles and almost 18% of the research has been published in journals of chemical engineering. 29 1.4.1 Biomedical applications. The incorporation of PANI into the hydrogel matrix allows reduction of mismatch at the interface with biological cells and tissues, and the movement of nutrients, medicines, and metabolites.…”

“…22 CPHs have also been utilized in designing energy storage devices, 23 microbial fuel cells, 24 and molecular/bioelectronics devices. 25 Among the several conducting polymers, polypyrrole (PPy), 26 polythiophene (PTh), 27 polyethylenedioxy thiophene (PEDOT), 28 polyaniline (PANI) 29 has been extensively investigated due to its ease of processibility, the ability to exist in various redox forms. Lately, PANI has been widely explored for its potential application as a supercapacitor and also in designing microbial fuel cells.…”

“…Approximately 503 publications are available on PANI hydrogels in the year 2021 with a total of 5386 citations. 29 Among the disciplines, almost 185 articles are published under Materials Chemistry discipline, while 135 articles are published under Physical Chemistry category and around 76 articles are available under the nanoscience/nanotechnology category, Fig. 1 .…”
