Area of Science:

  • Biotechnology
  • Microfluidics
  • Immunodiagnostics

Background:

  • Current immunoassay platforms face limitations in throughput and multiplexing capabilities.
  • There is a need for advanced tools to simultaneously quantify numerous biomarkers across multiple samples efficiently.

Purpose of the Study:

  • To develop and validate a high-throughput microfluidic platform for multiplexed immunoassays.
  • To demonstrate the platform's capability for simultaneous quantification of multiple biomarkers in distinct samples.

Main Methods:

  • A microfluidic device with 384 individually programmable unit cells was designed.
  • Each unit cell features four independent MITOMI detection areas for parallel sample analysis.
  • The platform supports pre-assembly and storage, with antibody pairs programmed for specific biomarker capture and detection.

Main Results:

  • The platform can quantify up to 384 biomarkers in 4 distinct samples, totaling 1,536 assays per device.
  • Proof-of-concept experiments successfully quantified Interleukin-6 (IL-6), Interleukin-1 beta (IL-1β), Tumor Necrosis Factor alpha (TNF-α), Prostate-Specific Antigen (PSA), and Green Fluorescent Protein (GFP).
  • The device demonstrated stability over weeks at elevated temperatures and was used to screen 64 antibody combinations for functional pairs.

Conclusions:

  • The developed microfluidic platform offers a robust and scalable solution for high-throughput biomarker analysis.
  • Its ability to perform multiplexed immunoassays and screen antibody combinations provides significant advantages for biological research and diagnostic applications.
