    Single-Droplet Microsensor for Ultra-Short Circulating EFGR Mutation Detection in Lung Cancer Based on Multiplex EFIRM Liquid Biopsy by Fang Wei, Peter Yu, Jordan Cheng, Feng Li, David Chia, David T. W. Wong

    Published 2023-06-01
    “…Broadly speaking, the unmet need in liquid biopsy lung cancer detection is the lack of a multiplex platform that can detect a mutation panel of lung cancer genes using a minimum amount of sample, especially for ultra-short ctDNA (usctDNA). Here, we developed a non-PCR and non-NGS-based single-droplet-based multiplexing microsensor technology, “Electric-Field-Induced Released and Measurement (EFIRM) Liquid Biopsy” (m-eLB), for lung cancer-associated usctDNA. …”
