Microfluidic Electronic Detection of Protein Biomarkers


Authors: Dan Wu, Brian Brandt, Joel Voldman

Immunoassays use antibodies to detect protein biomarkers, with a substantial market and significant clinical importance. However, traditional immunoassays are performed in centralized laboratories using optical methods; which mean results take days and it cannot be highly multiplexed, in turn increasing patient visits, healthcare costs, and decreasing healthcare outcomes. We are developing an all-electronic immunoassay with which we can 1) achieve high-throughput, potentially measuring all protein biomarkers in blood samples; 2) reduce cost by taking advantage of the decreasing cost of silicon electronics; 3) deliver results to patients before they meet with their physicians.
