et al.

Abstract: In this work, poly(sodium 4-styrenesulfonate) (PSS)-encapsulated acridinium sulfonamide (AS)-functionalized CoFe 2 O 4 nanoparticles (CoFe 2 O 4 /AS/PSS NPs) were synthesized by a layer-by-layer assembly strategy. Compared with previously reported chemiluminescence (CL)-functionalized magnetic nanomaterials, CoFe 2 O 4 /AS/PSS NPs exhibited a high CL intensity with a much lower synthetic concentration of CL reagent and shorter synthetic time. The reason was found to be attributed to the high loading efficiency… Show more

“…Chemiluminescence (CL) technology has been extensively used in the domain of analysis due to its high sensitivity, simple instrumentation, and absence of background scattered light for detecting trace level metal ions, inorganic compounds, and small biological molecules. Although many technologies have been applied in the field of detection, the CL method exhibits higher sensitivity due to the low background emission. Whereas, traditional CL systems are limited in practical applications due to the low inherent signal and poor selectivity.…”
