我们开发了一种新的和通用的方法来设计一个无标记的荧光Cu(II)传感器的基础上内部的DNA切割和一个外在的荧光团在石墨烯/DNAzymes复合物具有高灵敏度和选择性。
We developed a novel and general methodology to design a label-free fluorescent Cu(II) sensor based on internal DNA cleavage and an extrinsic fluorophore in a graphene/DNAzymes complex with high sensitivity and selectivity.
