“…These solutions were prepared to determine the maximum wavelength of rhodamine B and as a database for the TCS3200 color sensor. Following that, a solution of 1 mL ZnCl 2 2 M and 2 mL KCNS 2 M as a reagent was made to detect the presence of rhodamine B, as suggested by a previous report [23].…”

The use of the notorious synthetic dye, rhodamine B, in food and beverage products has been widely reported. This application urges the need to develop an analytical method that can provide reliable rhodamine B data with an easy operational technique. Therefore, this research is aimed to develop an Arduino Uno-based TCS3200 color sensor and study its application to determine rhodamine B levels in syrup. The design of the analytical instrument included TCS3200, an Arduino Uno microcomputer, an Integrated Development Environment (IDE) software, a black box container, and a 24 × 2 matrix display screen, where samples were prepared via absorption using wool thread. With a linear range of 1–20 mg/L, our proposed colorimetric sensor had recoveries of 96.25–110.3%, which was better compared to that was obtained from the UV-vis (81.8–100.6%) method. The detection and quantification limits of the sensor were 2.766 and 8.383 mg/L, respectively. The syrup samples used in this study were purchased from the local stores in Banda Aceh. Based on the proposed TCS3200 color sensor, the highest rhodamine B concentration from the syrup sample was 16.74 mg/L. The t-test analysis in this study revealed that the Rhodamine B levels quantified using the newly developed TCS3200 color sensor were not statistically or significantly different from the UV-Vis spectrophotometer method.

“…The quenching of uorescence intensity may be due to the interactions between imine group and Cu 2+ /Hg 2+ (Scheme 2), where paramagnetic effect of Cu 2+ and heavy metal effect of Hg 2+ might be responsible for this observed quenching [43,44].…”

A simple uracil-appended uorescent sensor (1) has been developed by one pot reaction and characterized by using common spectroscopic methods such as UV-vis, Fluorescence, HRMS and FT-IR spectroscopies. Upon addition of various metal ions to the CH 3 CN solution of sensor 1, the uorescence was quenched in the presence of Cu 2+ / Hg 2+ ions. The limit of detection for Cu 2+ and Hg 2+ was calculated to be 3.31 and 0.316 µM, respectively. Further, the sensor was applied for real-life applications in the determination of Vitamin B 2 (ribo avin) and its presence in milk products. On the incorporation of different sources of vitamin-B to acetonitrile solution of it, there was discernible uorescence enhancement only in the presence of vitamin B 2 . Also, it has been successfully applied for the detection of Vitamin B 2 (ribo avin) in milk and curd. Moreover, based on the uorescent color changes, the sensor was utilized for invisible ink applications.
