Electrochemical immunoassay for the tumor marker CD25 by coupling magnetic sphere-based enrichment and DNA based signal amplification
Interleukin-2 receptor alpha chain (also called CD25) is a tumor biomarker that is frequently expressed on the surface of hematological tumor cells. The authors describe an electrochemical immunoassay for CD25...

Coupling antibody based recognition with DNA based signal amplification using an electrochemical probe modified with MnO2 nanosheets and gold nanoclusters: Application to the sensitive voltammetric determination of the cancer biomarker alpha fetoprotein
The authors describe a sensitive electrochemical immunoassay for the cancer biomarker α-fetoprotein (AFP). It is based on a combination of an immunoassay with DNA-based signal amplification. Two-dimensional MnO2 ...
