Area of Science:

  • Optoelectronics
  • Microfluidics
  • Lab on a Chip technology

Background:

  • Current Lab on a Chip solutions lack integrated optical detection for microfluidic droplets.
  • Droplet analysis often relies on imaging techniques, which are hindered by time-consuming data processing and storage.

Purpose of the Study:

  • To develop a fully integrated opto-microfluidic platform for droplet detection, labeling, and characterization.
  • To overcome the limitations of imaging-based droplet monitoring in microfluidic systems.

Main Methods:

  • Designed an opto-microfluidic platform integrating optical waveguides in a Mach Zehnder configuration with a microfluidic circuit on a single substrate.
  • Utilized lithium niobate crystals for sensor fabrication, ensuring chemical resistance and biocompatibility.

Main Results:

  • Demonstrated simultaneous, real-time labeling and identification of individual droplets based on optical properties.
  • Successfully characterized droplet velocity and dimensions without employing imaging techniques.

Conclusions:

  • The developed opto-microfluidic platform offers a non-imaging solution for comprehensive droplet analysis.
  • The use of lithium niobate allows for future integration of multifunctional stages, expanding device applicability.
