Overview

Experimental evaluation reveals cicada wings' nanopillar array reduces biofilm formation in gram-positive bacteria, indicating a novel antifouling strategy.

Key Points

  • To assess the mechano-bactericidal activity of cicada wing nanostructures against gram-positive bacteria.
  • Evaluated bactericidal efficacy using live/dead staining on Bacillus cereus and Staphylococcus aureus.
  • Visualized bacteria–structure interaction with scanning electron microscopy and transmission electron microscopy.
  • Investigated the physical disruption mechanism on bacterial integrity.
  • Cicada wing nanopillar array significantly reduced biofilm formation in gram-positive bacteria.
  • Bacillus cereus demonstrated higher killing efficiency compared to Staphylococcus aureus.
  • The mechanism of action involved physical disruption rather than chemical composition.
