Hg(2+) was found to specifically induce the aggregation of perylene bisimide in a "thymine-Hg(2+)-thymine" binding motif and the resultant aggregates showed a highly selective and sensitive turn-on fluorescence response for cysteine, with a detection limit down to 9.6 nM.
汞离子（Hg(2+)）被发现能够特异性诱导并四苯二酰亚胺（perylene bisimide）在“胸腺嘧啶-Hg(2+)-胸腺嘧啶”结合基序中聚集，所得的聚集物对半胱氨酸表现出高度选择性和灵敏的荧光响应，检测限低至 9.6 nM。
