Abstract
P-nitrophenol (p-NP) is a hazardous chemical contaminant that can enter the body and cause health issues. The current sensor for detecting p-NP is complex to operate and cannot be used on-site. Therefore, it is essential to develop a highly sensitive and selective material for the determination of p-NP in real-time, such as a fluorescence sensor. Carbon dots (CDs) possess exceptional photoluminescence (PL) properties, making them promising for sensing applications. This review presents the recent advancement, synthesis strategies, and optical properties of CDs fluorescence sensors. Additionally, we enlighten the application and current challenges of the use of CDs as a sensor for detecting p-NP.
