RT Journal Article T1 Binary MoS2 nanostructures as nanocarriers for amplification in multiplexed electrochemical immunosensing: simultaneous determination of B cell activation factor and proliferation-induced signal immunity-related cytokines A1 Arévalo Pérez, Beatriz A1 Blázquez García, Marina A1 Valverde De La Fuente, Alejandro A1 Serafín González-Carrato, Verónica A1 Montero Calle, Ana A1 Solís Fernández, Guillermo A1 Barderas Manchado, Rodrigo A1 Campuzano Ruiz, Susana A1 Yáñez-Sedeño Orive, Paloma A1 Pingarron, José M. AB A dual immunosensor is reported for the simultaneous determination of two important immunity-related cytokines: BAFF (B cell activation factor) and APRIL (a proliferation-induced signal). Sandwich-type immunoassays with specifc antibodies (cAbs) and a strategy for signal amplifcation based on labelling the detection antibodies (dAbs) with binary MoS2/ MWCNTs nanostructures and using horseradish peroxidase (HRP) were implemented. Amperometric detection was carried out at screen-printed dual carbon electrodes (SPdCEs) through the hydroquinone HQ/H2O2 system. The developed dual immunosensor provided limit of detection (LOD) of 0.08 and 0.06 ng mL−1 for BAFF and APRIL, respectively, and proved to be useful for the determination of both cytokines in cancer cell lysates and serum samples from patients diagnosed with autoimmune diseases and cancer. The obtained results agreed with those found using ELISA methodologies.
