Electrochemical preparation of polyaniline microspheres incorporated with DNA

Preparation of gold nanoparticles/single-walled carbon nanotubes/polyaniline composite-coated electrode developed for DNA detection

“…Singlewalled carbon nanotubes-conducting polymer, poly(vinylferrocenium)-modified pencil graphite electrodes have been prepared by Muti et al for DNA hybridization detection [35]. The electrochemical polymerization of aniline in the presence of DNA has been performed to synthesize a structurally controlled PANI/DNA composite material by Yano et al [36].…”

Nitrogen-doped carbon nanotube/polyaniline composite: Synthesis, characterization, and its application to the detection of dopamine

“…Moreover, it has been demonstrated that the doping of nitrogen enhances the biocompatibility and sensitivity of CNTs in biosensing field [9]. Polyaniline (PANI) is one of the most important conducting polymers and has been researched intensively over the past few years due to its ease of synthesis, well electronic and optical properties [10] and environmental stability [11]. Although PANI has many advantages and holds high position among the conducting polymers owing to its unique tunable conductivity either by protonic acid doping or redox doping, its electroactivity can only be retained in acidic media, normally at pH < 4.0 [7].…”
