“…Environmental pollution is another global concern issue. Because of the abused mining and uncontrolled discharge of polluted water, versatile pollutes, such as heavy metal ions, organic dyes, and antibiotics have been draining into water and soil and then entering the human body through the chain of the ecological system. − As a heavy metal ion, Ag + ion exhibits a strong affinity with various metabolites including imidazole, amine, carboxyl, and inactive sulfhydryl enzymes, hence resulting in toxicity to the human organism like epilepsy, argyria, and kidney/liver failure. − To date, some analytical methods, such as atomic absorption spectroscopy, inductively coupled plasma mass spectrometry, and surface-enhanced Raman spectroscopy have been exploited to detect Ag + . − But the development of an efficient method with high sensitivity and selectivity for the recognition of Ag + is strongly desired.…”
