A new modified mesoporous silica nanosensor was synthesized by the co-condensation method. Under basic conditions, the obtained mesoporous silica nanosensor responds selectively to Fe(2+) (pH = 8) and Cu(2+) (pH = 12) with a distinguishable colour change perceivable by the naked eye and a detection limit of approximately 50 ppb.
一种新型的改良介孔硅纳米传感器通过共缩聚方法合成。在碱性条件下，所得到的介孔硅纳米传感器对 Fe(2+)（pH=8）和 Cu(2+)（pH=12）具有选择性响应，肉眼可见明显的颜色变化，检测限约为 50ppb。
