Abstract

Hızlı sanayileşme, endüstriyel atıklardan kaynaklanan sentetik boyaların su kütlelerini kirletmesi gibi ciddi çevresel sorunlara neden olmuştur. Bu boyalar, kanserojen ve mutajenik etkiler gibi sağlık riskleri taşır ve ekolojik sorunlara yol açmaktadır. Metilen mavisi (MB) gibi yaygın boyalar, çok toksik olmasa da uzun süreli maruz kalma durumunda zararlı olabilir. Bu çalışma, MB'nin hassas tespiti için Polidopamin-Nikel (PDA-Ni) manyetik mikromotorların geliştirilmesine odaklanmaktadır. Elektrokimyasal şablon yöntemiyle üretilen bu mikromotorlar, kendi kendine hareket ederek sulu çözeltilerde yüksek MB konsantrasyonlarını etkili bir şekilde tespit edebilir. Mikromotorların tübüler yapısı, daha fazla adsorpsiyon kapasitesi için geniş bir yüzey alanı sunar. Döngüsel voltametri ile yapılan analizler, mikromotorların geniş bir MB konsantrasyon aralığında yüksek hassasiyet ve kararlılık gösterdiğini ve 0.1 µM tespit sınırına sahip olduğunu göstermektedir. Bu çalışma, PDA-Ni mikromotorların çevresel izleme ve kirletici gideriminde potansiyelini vurgulamakta ve su kirliliğinin yönetimi için umut verici bir çözüm sunmaktadır.

Polydopamine-Nickel Magnetic Micromotors for Efficient Detection of Methylene Blue Dye

Abstract

Rapid industrialization has led to significant environmental challenges, such as the pollution of water bodies by synthetic dyes from industrial waste. These dyes pose health risks, including carcinogenic and mutagenic effects, and contribute to ecological problems. Common dyes like methylene blue (MB), while not highly toxic, can be harmful with prolonged exposure. This study focuses on developing polydopamine-nickel (PDA-Ni) magnetic micromotors for the sensitive detection of MB. These micromotors, produced using an electrochemical template method, can autonomously move and effectively detect high concentrations of MB in aqueous solutions. The tubular structure of the micromotors provides a large surface area for increased adsorption capacity. Electrochemical analyses using cyclic voltammetry show that the micromotors exhibit high sensitivity and stability across a wide range of MB concentrations, with a detection limit of 0.1 µM. This study highlights the potential of PDA-Ni micromotors in environmental monitoring and pollutant removal, offering a promising solution for managing water pollution.
