    This study integrates microfluidic impedance cytometry (MIC) with deep learning (DL) for robust cell signal segmentation. An encoder-decoder DL model achieved high accuracy, enabling cross-setup generalizability for advanced single-cell analysis.

    Area of Science:

    • Biotechnology
    • Data Science
    • Bioinformatics

    Background:

    • Microfluidic impedance cytometry (MIC) is a label-free, high-throughput method for single-cell analysis.
    • Current MIC signal processing lacks a universal approach due to setup-dependent signal characteristics.
    • Effective signal segmentation is crucial for the entire MIC data processing workflow.

    Purpose of the Study:

    • To investigate the integration of deep learning (DL) with MIC for robust signal processing.
    • To develop a universal signal segmentation framework for diverse MIC systems.
    • To address the challenge of cross-setup generalizability in MIC data analysis.

    Main Methods:

    • Collected impedance data from multiple experimental MIC setups.
    • Developed and compared various DL models, including recurrent, convolutional, and encoder-decoder networks.
