Polydimethylsiloxane (PDMS) is popular for microfluidics but its hydrophobicity limits performance. Researchers are developing durable surface modifications for enhanced PDMS microfluidic devices.

Area of Science:

  • Materials Science
  • Microfluidics
  • Surface Chemistry

Background:

  • Polydimethylsiloxane (PDMS) is widely used in microfluidics due to its favorable properties like low cost and optical transparency.
  • However, PDMS's inherent hydrophobicity and rapid hydrophobic recovery hinder the performance of microfluidic devices.
  • This necessitates research into stable surface modifications for PDMS.

Purpose of the Study:

  • To review recent advancements in surface modification techniques for PDMS.
  • To highlight methods that overcome PDMS hydrophobicity and improve microfluidic device performance.
  • To discuss the applications and future potential of modified PDMS surfaces.

Main Methods:

  • Review of surface modification techniques including metal coatings, layer-by-layer deposition, surfactant treatments, and protein adsorption.
