Abstract
Herein, we checked if the existing mercury sensor (R) could be applied for the detection of Ni2+ ion in both colorimetrically as well as fluorimetrically. The fluorescent detection limit for Ni2+ ion is as low as 8.62 × 10−7 M, which is lower than the guideline for drinking water (1.2 × 10−6 M) by American Environmental Protection Agency (EPA). All the findings were theoretically supported using Density Functional Theory (DFT) studies. The sensing ability of R for Ni2+ was effectively applied to real water samples. Based on the color changing and spectral response in this method, we investigated molecular logic gates with single and dual input signal amplification by employing chemical input (Ni2+) and light input (UV). Furthermore, test kits containing R were constructed, which could perform as a suitable and competent analysis for “in-the-field” measurement of Ni2+. © 2019 Elsevier Ltd
