Main Results:

  • The microfluidic chip exhibited high flexibility.
  • Microstructures showed greater deformation than the chip itself due to stress concentration.
  • Successful dynamic manipulation (trapping and releasing) of single cells was achieved by simple chip stretching.

Conclusions:

  • Flexible elastomer microfluidic chips offer novel capabilities for cell manipulation.
  • The developed chip design facilitates precise control over single cells through mechanical deformation.
  • This approach advances the potential of lab-on-a-chip systems for cell-based assays and diagnostics.
