摘要：

A new modified mesoporous silica nanosensor was synthesized by the co-condensation method. Under basic conditions, the obtained mesoporous silica nanosensor responds selectively to Fe2+ (pH = 8) and Cu2+ (pH = 12) with a distinguishable colour change perceivable by the naked eye and a detection limit of approximately 50 ppb.
