“…Synergic effect in the nanomaterial-polymer ensured good contact and high electron transfer rate. A similar composite PANI-nickel nanoparticles was reported for glucose detection [179]. Face-centered cubic nickel oxide was dispersed in the polymer matrix which catalyzed the glucose reaction with respect to the bare electrode increasing with the pH value of the solution.…”

Electrochemical sensors appear as low-cost, rapid, easy to use, and in situ devices for determination of diverse analytes in a liquid solution. In that context, conducting polymers are much-explored sensor building materials because of their semiconductivity, structural versatility, multiple synthetic pathways, and stability in environmental conditions. In this state-of-the-art review, synthetic processes, morphological characterization, and nanostructure formation are analyzed for relevant literature about electrochemical sensors based on conducting polymers for the determination of molecules that (i) have a fundamental role in the human body function regulation, and (ii) are considered as water emergent pollutants. Special focus is put on the different types of micro- and nanostructures generated for the polymer itself or the combination with different materials in a composite, and how the rough morphology of the conducting polymers based electrochemical sensors affect their limit of detection. Polypyrroles, polyanilines, and polythiophenes appear as the most recurrent conducting polymers for the construction of electrochemical sensors. These conducting polymers are usually built starting from bifunctional precursor monomers resulting in linear and branched polymer structures; however, opportunities for sensitivity enhancement in electrochemical sensors have been recently reported by using conjugated microporous polymers synthesized from multifunctional monomers.

“…It was reported that the NiO/6% PANI showed superior catalytic ability, which was explained by the increased surface area leading to better electron transfer. The obtained sensors had sensitivity of 606.13mA mM -1 cm -2 with an LOD of 0.19 μM [ 165 ]. Balasubramanian et al fabricated thin nanosheets of cobalt hydroxide rich in Co vacancies.…”

Biosensors have potentially revolutionized the biomedical field. Their portability, cost-effectiveness, and ease of operation have made the market for these biosensors to grow rapidly. Diabetes mellitus is the condition of having high glucose content in the body, and it has become one of the very common conditions that is leading to deaths worldwide. Although it still has no cure or prevention, if monitored and treated with appropriate medication, the complications can be hindered and mitigated. Glucose content in the body can be detected using various biological fluids, namely blood, sweat, urine, interstitial fluids, tears, breath, and saliva. In the past decade, there has been an influx of potential biosensor technologies for continuous glucose level estimation. This literature review provides a comprehensive update on the recent advances in the field of biofluid-based sensors for glucose level detection in terms of methods, methodology and materials used.

“…A polymer-incorporated nanomaterial is frequently utilized to ameliorate the conductivity and catalytic tendency of sensors and to drastically increase the strength of the electrochemical transmission when developing nanocomposites based on metal oxide/copper oxide [9]. For instance, polymers such as PEG [10], PVP [11], PVA [12], PAA [13], and polyaniline (PANI) [14] are effectively used in the fabrication of a biosensor. The polymer plays a huge attention in electrochemical sensor because of the unique characters of polymer such as conductive nature, compatibility, electron supporter, and inexpensive [15,16].…”

At present, the determination of dopamine (DA) is enormously necessary for the human body. Since then, it has played a crucial role in the brain that affects mood, sleep, memory, learning, and concentration. Dopamine insufficiency is a threat to human health. Dopamine recognition is important to avoid this problem. Copper oxide (CuO) nanoparticles are one of the potentials which can be used in the detection of dopamine level in the sample. In this work, CuO was synthesized by a simple chemical precipitation technique and modified by polyvinyl alcohol (PVA) as a capping agent. The nanomaterials manufactured are used for the detection of dopamine in 0.1 M PBS medium at room temperature. The CuO/PVA-modified electrode shows better electrocatalytic activity than CuO/GCE (glassy carbon electrode). The constructed dopamine biosensor of copper oxide-PVA nanocomposites also has extraordinary selectivity, stability, sensitivity (183.12 μA mM-1 cm-2), and a minimum level detection limit of 0.017 μM, is inexpensive, and has minimal effort and rapid detection of dopamine.
