Abstract

In this study, multiple nanodisc platinum electrodes were produced using the laser drawing technique to bring together multiple microwires in a single structure. The produced electrodes were characterized using cyclic voltammetry (CV) and scanning electron microscopy (SEM). Ferrocene dissolved in acetonitrile has been used as a redox mediator due to its reversible electron transfer properties. Voltammetric responses showed the steady-state behavior characteristic of the nanoelectrodes, and the obtained current values were used to estimate the effective electrode radius. According to the cyclic voltammetric results, the steady-state currents of the dual and triple platinum nanoelectrodes were approximately two and three times higher, respectively, than that of the single platinum nanoelectrode. SEM analysis confirmed the formation of multiple nanodisc structures with uniform distribution. The developed method provides a simple and reproducible approach for fabricating multiple nanoelectrode systems with potential applications in electrochemical sensing and nanoelectrochemistry.

Özet

Bu çalışmada, çoklu nanodisk platin elektrotlar, birden fazla mikro-telin tek bir yapıda biraraya gelmesi amacıyla lazer çekme tekniği kullanılarak üretilmiştir. Üretilen elektrotlar dönüşümlü voltametri (CV) ve taramalı elektron mikroskobu (SEM) kullanılarak karakterize edilmiştir. Asetonitrilde çözünmüş ferrosen, tersinir elektron transfer özelliklerinden dolayı redoks aracısı olarak kullanılmıştır. Voltametrik tepkiler, nanoelektrotların kararlı durum davranış karakteristiğini göstermiş ve elde edilen akım değerleri, etkili elektrot yarıçapını tahmin etmek için kullanılmıştır. Dönüşümlü voltamerrik sonuçlara göre, ikili ve üçlü platin nanoelektrotların kararlı durum akımlarının tekli platin nanoelektrodun kararlı durum akımının sırasıyla yaklaşık iki ve üç katı olduğu görülmüştür. SEM analizi, tekdüze dağılıma sahip çoklu nanodisk yapılarının oluşumunu doğrulamıştır. Geliştirilen yöntem, elektrokimyasal algılama ve nanoelektrokimyadaki potansiyel uygulamalara sahip çoklu nanoelektrotlu sistemlerin üretilmesi için basit ve tekrarlanabilir bir yaklaşım sağlamaktadır.
