Researchers developed a streamlined polystyrene (PS) microfluidic device fabrication process, matching poly(dimethylsiloxane) (PDMS) methods in cost and time. This advance enables more robust and complex microfluidic systems for cell-based studies.

Area of Science:

  • Materials Science
  • Biotechnology
  • Engineering

Background:

  • Microfluidic cell-based systems offer precise control and high throughput for biological studies.
  • Poly(dimethylsiloxane) (PDMS) is widely used but has limitations hindering microfluidic platform potential.
  • Polystyrene (PS) offers advantages but requires optimized fabrication methods.

Purpose of the Study:

  • To present a complete, cost-effective, and time-efficient fabrication process for polystyrene (PS) microfluidic devices.
  • To develop methods for PS microfluidics that rival PDMS in robustness, complexity, and speed.
  • To demonstrate the versatility of the optimized PS fabrication for cell-based applications.

Main Methods:

  • Adapted lithography to create robust epoxy molds for high-temperature/pressure embossing.
