Implication

Randomized trial demonstrates effective chromium detection using sustainable carbon dots, indicating a promising eco-friendly solution.

Key Points

  • This research aims to develop a sustainable method for synthesizing carbon quantum dots (CQDs) for detecting chromium ions in water.
  • Synthesis of edible fungus-based carbon quantum dots (Ef-CQDs) via a hydrothermal approach
  • Use of Ef-CQDs for selective fluorescence detection of Cr3+ in environmental water samples
  • Evaluation of antioxidant activity against hydroxyl and DPPH radicals
  • Ef-CQDs achieved Cr3+ detection with spiked recoveries of 95.2% to 100.6% in real water samples
  • The Ef-CQDs showed high selectivity towards Cr3+ compared to other metal ions
  • Significant antioxidant activity was demonstrated by the Ef-CQDs against radicals.
