Main Results:

  • The fabricated whole-Teflon chips demonstrated outstanding inertness to various chemicals and extreme resistance to all solvents.
  • Teflon chips showed no absorption of small molecules, minimal adsorption of biomolecules, and no leaching of residue molecules.
  • Biological cells, including adherent cells, were successfully cultured, attaching, spreading, and proliferating well in the Teflon channels, comparable to PDMS channels.

Conclusions:

  • Whole-Teflon microfluidic chips with integrated valves offer significant advantages over traditional materials like PDMS.
  • These Teflon chips are suitable for a wide range of applications requiring chemical inertness, solvent resistance, and biocompatibility, including long-term cell culture.
