Electrosynthesis of electrochemically reduced graphene oxide/polyaniline nanowire/silver nanoflower nanocomposite for development of a highly sensitive electrochemical DNA sensor

Abstract

A novel nanostructured material based on ERGO/PANi NWs/AgNFs was electrosynthesized on a Pt microelectrode and was used for the first time to develop an electrochemical DNA sensor.

Strategies for the preparation of non-amplified and amplified genomic dengue gene samples for electrochemical DNA biosensing applications

“…Most recent works related to electrochemical DNA biosensors have focused on studying miniaturized electrochemical sensor devices, 22 amplification signals, 23,24 biorecognition probes with new detection mechanisms, 25 and the optimization of immobilization and hybridization conditions. 26 However, far too little attention has been focused on the preparation of genomic DNA samples for electrochemical detection.…”

A glassy carbon electrode modified with polyaniline nanowires: An electrochemically effective surface area and an electrocatalytic activity for the oxidation of methanol under alkaline conditions

“…4 It is used in diverse applications such as sensors, nano-electronic devices, electron-field emitters, data storage devices, actuators, membranes, rechargeable batteries, supercapacitors, and catalysts. [5][6][7][8] Direct methanol fuel cells (DMFCs) are essential alternative power sources for portable and small-sized electronic devices. Composites based on platinum nanoparticles (PtNPs) are the most active electrocatalysts for the methanol electro-oxidation reaction in DMFCs.…”

Development of a Novel Electrochemical Sensor Based on Functionalized Carbon Black for the Detection of Guanine Released from DNA Hydrolysis

“…As described by Mohammadi et al [11], nanomaterials are the most used amplifiers with a 50 % compared to other amplification methods, owing to their role as accumulation platforms, carriers of signal elements, catalysts, and facilitators for enhanced electron transfer. In this case, there are non-carbon nanomaterials, such as gold, silver, magnetic nanoparticles, and molybdenum disulfide (MoS 2 ), and carbon nanomaterials such as multi/single-walled carbon nanotubes, graphene oxide/reduced graphene oxide [12][13][14][15][16][17][18][19], or carbon-based nanocomposites. Recently, a novel nanomaterial has been the subject of research, namely, carbon black [20,21], due to its electrical efficiency, chemical stability, high conductivity, high specific surface area, and low price.…”
