An ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV.
Biosens. Bioelectron. 42 , 136-40, (2013) We report on an ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV based on ligand exchange mechanism. Calcein as a fluorescence indicator and Sudan I-IV as model analytes were employed to investigate ... |
