Highly sensitive turn-on biosensors by regulating fluorescent dye assembly on liposome surfaces
CHEMICAL COMMUNICATIONS(2015)
摘要
We developed a new self-signaling sensory system built on phospholipid liposomes having H-aggregated R6G dyes on their surface. Selective molecular recognition of a target by the phospholipid displaces R6G from the liposome surface to turn on fluorescence signal. Selective and sensitive detection of neomycin down to 2.3 nM is demonstrated.
