“…The biosensors based on conducting polymers were discovered to treat penicillin and detect innumerable chromosomal disorders. A highly sensitive and rapid flow injection system for urea analysis was fabricated using the composite film of polypyrrole and a polyion complex [ 97 ]. Glucose biosensors are used to estimate glucose by the arrest of glucose oxidase enzymes with conducting polymers.…”

Electrically-conducting polymers (CPs) were first developed as a revolutionary class of organic compounds that possess optical and electrical properties comparable to that of metals as well as inorganic semiconductors and display the commendable properties correlated with traditional polymers, like the ease of manufacture along with resilience in processing. Polymer nanocomposites are designed and manufactured to ensure excellent promising properties for anti-static (electrically conducting), anti-corrosion, actuators, sensors, shape memory alloys, biomedical, flexible electronics, solar cells, fuel cells, supercapacitors, LEDs, and adhesive applications with desired-appealing and cost-effective, functional surface coatings. The distinctive properties of nanocomposite materials involve significantly improved mechanical characteristics, barrier-properties, weight-reduction, and increased, long-lasting performance in terms of heat, wear, and scratch-resistant. Constraint in availability of power due to continuous depletion in the reservoirs of fossil fuels has affected the performance and functioning of electronic and energy storage appliances. For such reasons, efforts to modify the performance of such appliances are under way through blending design engineering with organic electronics. Unlike conventional inorganic semiconductors, organic electronic materials are developed from conducting polymers (CPs), dyes and charge transfer complexes. However, the conductive polymers are perhaps more bio-compatible rather than conventional metals or semi-conductive materials. Such characteristics make it more fascinating for bio-engineering investigators to conduct research on polymers possessing antistatic properties for various applications. An extensive overview of different techniques of synthesis and the applications of polymer bio-nanocomposites in various fields of sensors, actuators, shape memory polymers, flexible electronics, optical limiting, electrical properties (batteries, solar cells, fuel cells, supercapacitors, LEDs), corrosion-protection and biomedical application are well-summarized from the findings all across the world in more than 150 references, exclusively from the past four years. This paper also presents recent advancements in composites of rare-earth oxides based on conducting polymer composites. Across a variety of biological and medical applications, the fact that numerous tissues were receptive to electric fields and stimuli made CPs more enticing.

“…1 This response has been exploited in many ammonia sensors. [2][3][4] Such ammonia sensors have also been used in combination with biological catalysts, that produce ammonia as a product of their reaction, to sense the substrate for these enzymes. An example is the case of urease to amperometrically sense urea.…”

Sustainable current generation from the ammonia–polypyrrole interaction

Although current production in response to a polypyrrole (PPy) surface interaction with ammonia has been exploited in different sensor configurations, the origin of current generation has yet to be characterized. One of the standing issues critical to the use of this PPy-ammonia current generation is the limited lifetime of the PPy in the presence of ammonia. Our investigations into a possible mechanism for this reaction and experimental results indicate that this current generation is significantly more sustainable in the presence of a reactive oxygen species. Increase in lifetime (up to 50 fold) for such current generation has allowed an investigation of the reaction at different ammonia concentrations and pHs. Such experimentation allows the further contemplation of the use of ammonia as a possible fuel in a room temperature and ambient pressure fuel cell without an anodic precious metal catalyst.
