    摘要: A first embodiment is a quantum dot-DNA-metallic ensemble that can be used as a fluorescent nanosensor for multiplexed detection of the presence and the quantity of one or more target ions in a single assay. In this design, DNA-functionalized multi-colored quantum dots are used as energy donors and god nanoparticles are used as energy acceptors. This design allows for flexibility and a selective binding of a target ion to oligonucleotides, drives the formation of DNA helixes, which bring a quantum dot and metallic nanoparticle into close proximity, leading to a fluorescence emission energy transfer. The energy transfer is detected and the presence and the quantity of the target ion can be confirmed.
