Levonorgestrel protected PtCu clusters were assembled with a polymer to prepare nanobeads (NBs) with intense red fluorescence. An immunofluorescence sensor based on PtCuNBs was established for the rapid and sensitive detection of interleukin-6 (IL-6) owing to its significance in inflammatory diseases, with a limit of detection of 42.66 pg mL. IL-6 spiked in serum was also accurately detected.
