What is Silver Nanoparticle Incorporated Colorimetric/fluorescence Sensor for Sub-ppb Detection of Mercury Ion via Plasmon-enhanced Fluorescence Strategy about?
Mercury released by industrial processes is a global pollution that threatens human health and the environment. In this study, a colorimetric and fluorescence sensor derived from rhodamine 6G thioamide (RS) was synthesized. The sensor displayed “turn on” fluorescence signaling with the detection limit of 0.49 ppb and the chromogenic change from colorless to pink upon selective sensing of mercury ion (Hg2+). In addition, utilizing plasmonic enhancement by incorporation of RS with the synthesized blue silver nanoparticle (B-AgNPs) to obtain RS + B-AgNPs led to larger emissive fluorescence quantum yield via non–radiative energy transfer, which consequently improved sensitivity of the sensor. RS + B-AgNPs provided approximated 16 times lower detection limit (0.030 ppb) compared to detection limit of the bare sensor. RS + B-AgNPs could be utilized to monitor contaminated Hg2+ in real samples, such as drinking water and seafood fillets. This result indicates that sensor RS + B-AgNPs can tolerate the interference from matrix of the real samples . Moreover, the paper test strip made from RS also demonstrated qualitative and quantitative screenings of Hg2+ with rapid colorimetric change, wh
