基于寡核苷酸的目标诱导构象变化以及氧化石墨烯对无结构DNA和G - 四链体DNA亲和力的差异，开发了一种用于Pb2 +的无标记、灵敏且具有选择性的荧光传感器。
A label-free sensitive and selective fluorescent sensor for Pb2+ was developed based on target-induced conformational change of an oligonucleotide and the difference in affinity of graphene oxide for unstructured and G-quadruplex DNA.
