From lab to life: Safe and efficient optical based dual-mode chemosensor for the detection of aluminium (III) and copper (II) ions

Phenothiazine appended thiophene derivative: a trilateral approach to copper ion detection in living cells and aqueous samples

“…Sequentially introducing the cupric ion and EDTA over four cycles resulted in emission shifts, encompassing both enhanced and quenched transitions. During those four cycles, it was evident that the transition in fluorescence emission had reversed, leading to a change in the color of fluorescence 35 ( Fig. 10B ).…”
