“…AB is a carbon nanomaterial which is a specific subtype of carbon black and is produced by the controlled combustion of acetylene under pressurized air. ABs are usually used as substitutes for graphitic powder in the preparation of carbon paste electrodes, − and are dispersed in chitosan solution to modify glassy carbon electrodes . An acetylene black–dihexadecyl hydrogen phosphate (AB–DHP) film-coated glassy carbon electrode (GCE) was also constructed to detect 2-chlorophenol and erythromycin …”

Research pertaining to conductive polymers has gained significant traction in recent years, and their applications range from optoelectronics to material science. For all intents and purposes, conductive polymers can be described as Nobel Prize-winning materials, given that their discoverers were awarded the Nobel Prize in Chemistry in 2000. In this review, we seek to describe the chemical forms and functionalities of the main types of conductive polymers, as well as their synthesis methods. We also present an in-depth analysis of composite conductive polymers that contain various nanomaterials such as graphene, fullerene, carbon nanotubes, and paramagnetic metal ions. Natural polymers such as collagen, chitosan, fibroin, and hydrogel that are structurally modified for them to be conductive are also briefly touched upon. Finally, we expound on the plethora of biomedical applications that harbor the potential to be revolutionized by conductive polymers, with a particular focus on tissue engineering, regenerative medicine, and biosensors.

“…6, HSA NP/p(CTAB)/PGE ile pH 4,0 BRT'de tarama hızının MP'nin pik akımı (Ip) üzerindeki etkisini incelemek için 10-200 mVs −1 aralığında kaydedilen voltammogramları göstermektedir. Katodik pik akımlarının, tarama hızı ile doğrusal olarak artması, MP'nin indirgenme kinetiğinin adsorpsiyon kontrollü davranış gösterdiği şeklinde yorumlandı[39]. Ayrıca, artan tarama hızıyla pik potansiyellerindeki kayma, indirgenme reaksiyonunun tersinmez olduğunu gösterdi.…”

Bu çalışmada, insan serum albümin nanopartiküller (HSA NP) ve elektrobiriktirilmiş yüzey aktif polisetiltrimetil amonyum bromür p(CTAB) film kaplı grafit elektrotlar (PGE) tehlikeli bir çevresel kirletici olan metil paratiyonun (MP) hassas ve seçici tespiti için elektrokimyasal sensör olarak kullanıldı. Elde edilen HSA NP/p(CTAB)/PGE mikroskopik ve elektrokimyasal olarak karakterize edildi. Diferansiyel puls voltametri (DPV) tekniği ile MP için elde edilen doğrusal çalışma aralığı 0,01-0,1 µM ve gözlenebilme sınırı ise 6 nM olarak tespit edildi. MP tespiti için geliştirilen enzim kullanımı gerektirmeyen ve basit hazırlama stratejisine sahip HSA NP/p(CTAB) tabanlı elektrokimyasal sensör, çevre koruma ve gıda güvenliği açısından izleme sürecini de basitleştirme potansiyeline sahiptir.

The preparation of stable oleic‐acid‐capped iron‐oxide nanoparticles is reported, which were further coated with cationic poly (d,l‐lactic‐co‐glycolic acid) and chitosan in aqueous media by using a nano‐emulsion technique. The prepared composite was used to modify a glassy carbon electrode and the electrochemical behavior and stability of modified electrode were investigated by using cyclic voltammetry. This platform was then utilized to prepare an electrochemical pesticide biosensor based on the inhibition study of the enzyme acetylcholinesterase. Furthermore, the response characteristics show that this fabricated electrode has a shelf life of about 3–4 months and has good adhesion properties along with homogeneous dispersion at the electrode surface. The linear range and detection limit for paraoxon pesticide detection was found to be 9.55–37.1 nM and 8.91 nM, respectively.
