Schematic representation of the sandwich immunoassays: a NbI-GR-GS-GCE as a PCT capturing sensor and CdTe@SiO2/NbII to detect the PCT by ECL. The preparation of the CdTe@SiO2/NbII is also shown (dashed line box) [72]. b Fabrication of the electrochemical immunosensor for the detection of PCT [73] c Principle for Electrochemical Immunoassay Based on Poly[G]-Functionalized Silica NPs [74] d Assembly procedure of ALP-Ab2-GNPs/PSA bioconjugates [75]
