- Abstract
- Owing to rapid climate change and increasingly stringent carbon regulations, carbon dioxide detection is becoming more important. In this study, we fabricate a cucurbit[6]uril-functionalized gold nanorod-based localized surface plasmon resonance (LSPR) gas sensor to detect carbon dioxide. The gold nanorods provide a high refractive index unit that enables the measurement of gas molecules with low molecular weights, while cucurbit[6]uril is a chemical receptor that binds to carbon dioxide owing to its structural characteristics. Therefore, cucurbit[6]uril was functionalized through direct adhesion on the surface of gold nanorods, which was replaced with citrate. The manufactured sensor can detect the presence of carbon dioxide at a maximum concentration of 400 ppm in the atmosphere. The high potential applicability of the cucurbit[6]urilapplied LSPR gas sensors is demonstrated in this study.
