|제목||Flexible and Reusable SERS Active Substrates for Detecting Formaldehyde Vapor|
|초록||As the most common aldehyde in the environment, formaldehyde (FA) is widely present in aquatic and air environments as one of the environmental pollutants. Owing to the influence of formaldehyde on nature and human bodies, a simple, rapid and highly sensitive method for the determination of formaldehyde vapor is urgently required. Surface enhanced Raman scattering (SERS) as a detection tool is the ability to selectively detect a target in any matrix.
In this study, we demonstrate a novel method for the fabrication of recyclable SERS-active substrate composed of Ag-coated TiO2 nanotube arrays. Such arrays exhibit superior detection sensitivity with high reproducibility and stability using SERS detection. This method will be applicable to the detection of other gases by choosing suitable probes.
