Main Methods:

  • Fabrication of microhole templates with adjustable aspect ratios using femtosecond laser double-pulse Bessel beams and chemical etching.
  • Demolding of polydimethylsiloxane (PDMS) micropillars using an inverted mold technology.

Main Results:

  • Achieved CFSA-MP with adjustable aspect ratios and ultrahigh mechanical robustness.
  • Demonstrated successful capture of microspheres with diameters ranging from 5 to 410 μm.
  • Expanded the height range of micropillars using Bessel optical fields, broadening captured object size range.

Conclusions:

  • The developed CFSA-MP technique offers size adjustability and high robustness.
  • This method significantly enhances the stability and durability of micropillar-based capture systems.
  • CFSA-MP shows great potential for applications in chemistry, biomedicine, and microfluidics.
