Abstract
Environmental appearance of antimicrobials due to frequent use of personal care products as recommended by WHO can cause serious flare-up of antimicrobial resistance. In this work, three eco-friendly microfabricated copper solid-state sensors were developed for measuring triclosan in water. Multi-walled carbon nanotubes were incorporated in sensor 2 and 3 as hydrophobic conductive inner layer. Meanwhile, β-cyclodextrin was incorporated in sensor 3 as an ionophore for selective binding of TCS in presence of interfering compounds. The obtained linear responses of sensors 1, 2 and 3 were (1 × 10− 8–1 × 10− 3 M), (1 × 10− 9–1 × 10− 3 M) and (1 × 10− 10– 1 × 10− 3 M), respectively. Limit of detection was 9.87 × 10− 9 M, 9.62 × 10− 10 M, and 9.94 × 10− 11 M, respectively. The miniaturized sensors were utilized for monitoring of triclosan in water samples. [ABSTRACT FROM AUTHOR]
