Overview

Novel method regulates coffee ring effect in colloidal droplets, improving particle patterning and biosensing applications.

Key Points

  • The porous hexagonal surface increased particle accumulation near the contact edge.
  • Nanoscale porosity significantly enhanced surface wettability and accelerated evaporation rates.
  • Hexagonal microstructures improved droplet stability, suppressing unwanted movements during evaporation.
  • This design can lead to advancements in surface-enhanced Raman scattering and other biosensing technologies.
