Main Methods:

  • Fabrication of cellulose acetate nanofibers at varying concentrations (15 wt%, 20 wt%, 30 wt%).
  • Surface modification to mimic celery structures.
  • Characterization using Scanning Electron Microscopy (SEM) and tensile testing.
  • Biocompatibility assessment through cell adhesion experiments.

Main Results:

  • Celery-like surface structures were successfully formed on cellulose acetate nanofibers.
  • Solvent evaporation and polymer concentration were identified as key factors influencing surface morphology.
  • The modified nanofibers demonstrated improved initial cell adhesion compared to unmodified fibers.
  • SEM and tensile tests confirmed the physical properties and structural integrity of the scaffolds.

Conclusions:

  • The developed celery-mimicking nanofiber surface structure enhances initial cell adhesion.
