Area of Science:

  • Analytical Chemistry
  • Microfluidics
  • Optics
  • 3D Printing

Background:

  • Traditional laboratory equipment for photometric analysis is often large, energy-intensive, and not suitable for on-site measurements.
  • There is a need for portable, low-cost analytical devices that can perform real-time, in-situ measurements.
  • Automation of micro-processes is crucial for improving efficiency and reducing resource consumption in analytical chemistry.

Purpose of the Study:

  • To develop and demonstrate a 3D printed opto-microfluidic autonomous analyzer for photometric applications.
  • To achieve automation of analytical micro-processes with a focus on small size and low energy consumption for portability.
  • To validate the device's performance for real-time, in-situ analysis, including auto-calibration and wireless communication.

Main Methods:

  • Design and fabrication of a 3D printed opto-microfluidic device.
  • Integration of four autonomous functions: control and data acquisition, hydrodynamic fluid pumping and flow injection, optical detection, and wireless communication.
  • Control of electronic systems using a virtual instrument interface.
  • Experimental validation using fluoride measurements.

Main Results:

  • The 3D printed analyzer demonstrated performance comparable to laboratory equipment for fluoride measurements.
  • Reagent consumption was reduced by 50%, and waste generation was reduced by 80%.
  • The cost of the portable microanalyzer is 75% lower than conventional laboratory equipment.

Conclusions:

  • The developed 3D printed opto-microfluidic analyzer offers a portable, autonomous, and cost-effective solution for photometric applications.
  • The device enables efficient on-site, real-time analysis with significant reductions in reagent use and waste.
  • This technology has the potential to democratize access to analytical instrumentation for various in-situ monitoring needs.
