Developing a tunable fluorosensor for Cu2 + ions Understanding the sensing mechanism in premicellar, micellar and post micellar SDS concentrations at different pH Electrostatic interactions among SDS, AMI and Cu2 + ions plays important role towards sensing application. Medium and SDS concentration dependent dual turn on/turn off fluorescence responses for Cu2 + ions
