A Point-of-Use Assay Based on Surface-Enhanced Raman Spectroscopy for Rapid Determination of Triclosan in Environmental Water and Mouthwash.

ABSTRACT: Triclosan, a widely used antibacterial agent found in many consumer and personal care products, is known to contaminate aquatic environments. This study introduces a point-of-use assay for detecting triclosan in personal care products and environmental water utilizing surface-enhanced Raman spectroscopy (SERS) technology with gold octahedra (AuOH) as the SERS-active substrate. Our innovative one-step detection strategy yields results within 8 min, demonstrating satisfactory recovery rates for triclosan in both water and mouthwash samples. The point-of-use assay showcases a robust correlation between the signal intensity and the logarithmic concentration of triclosan, ranging from 2 ppb to 5 ppm, achieving linearity (R ²) values exceeding 0.9, with acceptable reproducibili
