Title: Nanoparticle Labels/ Electrochemical Immunosensor for Detection of Biomarkers

Conference ·
OSTI ID:888704

A sensitive electrochemical immunosensor based on poly(guanine) functionalized silica nanoparticle label has been developed for the detection of protein biomarker, biomarker recombinant human tumor necrosis factor-a(TNF-a).This method is simple, selective, and reproducible for trace biomarker analysis. A remarkable LOD has been achieved through dual signal amplification by poly[G] functionalized silica NPs and catalytic guanine oxidation. The work demonstrates the feasibility of developing an inexpensive, sensitive, and portable device for multiplexed diagnoses of different protein biomarkers.
