Abstract
Photophysical properties of Rhodamine B bound to water-soluble polyanion sodium poly(4-styrenesulfonate) (PSS) in solution and Quartz/APES/PSS/RB SAMs were investigated. Experiments showed that Rhodamine B aggregated in Quartz/APES/PSS/RB SAMs and its fluorescence behavior was different from that in Quartz/APES/RB SAMs without PSS. The constructed Quartz/APES/PSS/RB SAMs were applied for label-free interfacial fluorescence sensing of DNA with extremely high sensitivity.
