Overview

One-step synthesis produces carbon quantum dots and nitrogen-doped variants, showing enhanced antibacterial activity against specific bacteria.

Key Points

  • N-doped carbon quantum dots demonstrated a significantly lower MIC of 0.06 mg/mL against Staphylococcus aureus.
  • The synthesis involves using dried mulberry extract, producing nanoparticles with diameters ranging from 0.5–4.5 nm for CQDs.
  • Photodynamic antibacterial tests revealed that reactive oxygen species production is higher in N-doped carbon quantum dots.
  • The study suggests potential applications of mulberry in synthesizing advanced materials for antimicrobial uses.
