Highly sensitive and selective electrochemical immunosensors by substrate-enhanced electroless deposition of metal nanoparticles onto three-dimensional graphene@Ni foams

Recent advances in biological molecule detection based on a three-dimensional graphene structure

“…For this requirement, the pure graphene structure detection substrate needs to be modified. Through doping metal nanoparticles, 83 heteroatom doping, 84 or special protein modification, 80 scientists are able to achieve many different kinds graphene composites with various unique functions. Moreover, the 3D structure increases the detection area, and improves the electron transmission efficiency.…”

“…In recent years, three-dimensional graphene materials have been widely used in gas sensing, 78 pressure sensing, 79 electrochemical biosensors 80 and other fields, especially in the field of electrochemical biosensors. Biosensing is crucial for improving the quality of human life.…”

Recent advances of peroxidase-active nanozymes in electrochemical immunoassays

“…[1][2][3] During the early stages of morbidity, the content of some proteins or metabolites, namely disease markers, closely related to the disease categories fluctuates markedly beyond the range of normal values. [4][5][6] Hence, precise monitoring for these biomarkers has become pivotal in preventing the deterioration of disease. [7][8][9] Recently, a variety of detection methods, including electrochemical immunoassay, [10][11][12] mass spectrometry immunoassay, 13 fluorescence immunoassay, 14 and electrochemiluminescence immunoassay, 15 have been widely developed for the accurate detection of disease markers.…”

Electrochemical Signal Substance for Multiplexed Immunosensing Interface Construction: A Mini Review

“…Cancer is one of the main causes of human death, and its accurate diagnosis always requires a comprehensive monitor for correlative biomarkers [ 1 , 2 , 3 ]. However, in the present detection of cancer biomarkers, most immunoassays have focused on the improvement of analysis performance, including the limit of detection, detection range, sensitivity or other parameters, and exploitation of novel immunoassay methodologies to contrapose the analysis of single tumor marker [ 4 , 5 , 6 , 7 ]. In fact, most cancers have more than one tumor marker associated with their occurrence, and many markers are correlated to more than one kind of cancer or disease condition [ 8 , 9 , 10 ].…”
