    Area of Science:

    • Biotechnology
    • Cell Biology
    • Microfluidics

    Background:

    • Studying in vivo relevant cell-cell and cell-extracellular matrix interactions requires precise control over cellular microenvironments.
    • Microfluidics offers high-throughput cell delivery, while laser-guided systems provide high spatial resolution for cell patterning.

    Purpose of the Study:

    • To design, construct, and evaluate a novel microfluidics-based cell-delivery biochip.
    • To develop a combined system integrating the biochip with laser-guided cell micropatterning.
    • To achieve precise placement of individual cells into 2D and 3D arrays.

    Main Methods:

    • A removable microfluidics-based cell-delivery biochip was designed and constructed.
    • The biochip was coupled with a laser-guided cell-micropatterning system.
    • Chick forebrain neurons and glial cells were delivered via microfluidic channels and patterned using laser guidance.

    Main Results:

    • The combined system successfully placed individual cells into 2D and 3D arrays with micron-level accuracy.
    • Single-cell manipulation occurred at speeds of 150 μm/s (radial) and 50 μm/s (axial).
    • Individual cells were patterned typically within 20-30 seconds.

    Conclusions:

    • Coupling microfluidics-based cell delivery with laser guidance enables highly accurate and reproducible cellular array construction.
    • This integrated system is a valuable tool for creating engineered microenvironments for studying cell interactions.
