A Direct Electrochemical Biosensing Platform Constructed by Incorporating Carbon Nanotubes and Gold Nanoparticles onto Redox Poly(thionine) Film

Gold nanoparticle-based electrochemical biosensors

“…In other configuration, a direct electrochemical biosensing platform was fabricated by covalent incorporation of CNTs and gold nanoparticles onto a GCE modified with electropolymerized poly(thionine). The synergic effects of the composite nanomaterials together with the excellent mediating ability of the redox polymer, allowed faster electron transfer and higher enzyme immobilization efficiency than the designed based on CNTs or gold nanoparticles, as it was demonstrated using HRP as a test enzyme model [28].…”

Electroreduction of oxygen on gold nanoparticle/PDDA-MWCNT nanocomposites in acid solution

“…A direct electrochemical biosensing platform has been fabricated by covalent incorporation of CNTs and AuNPs onto the poly(thionine) film deposited by electropolymerisation [21]. MWCNTs/thionine/AuNPs composites were prepared by non-covalent binding of AuNPs to the surface of thioninecoated CNTs [22].…”

Dopamin, NADH ve Askorbik Asitin Elektroyükseltgenmesine Elektrokimyasal Olarak İndirgenmiş Grafen Oksit, Politiyonin ve Altın Nanopartiküllerin Etkisi

“…Döngü 8(1), 8-23, 2021 BSEU Journal of Science https://doi.org/10.35193/bseufbd.822201 e-ISSN: 2458-7575 (https://dergipark.org.tr/tr/pub/bseufbd) sayısı arttıkça anodik ve katodik pik akımları da artmış ve polimer filmi büyümüştür. Elde edilen sonuçlara göre elektrot yüzeyinde PTH filmi oluşturulmuştur [22,41]. Politiyoninin pik akımlarındaki bu artış yalın SPCE'ye göre SPCE/ERGO'da daha fazladır.…”
