One-step fabrication of Chitosan–Copper SERS nanocomposites for pesticide and microplastic detection

Key Points

• Detection of pesticides and microplastics was significantly improved using chitosan-copper nanocomposites.
• A notable increase in sensitivity was achieved, indicating a promising metric for environmental monitoring.
• The observational analysis integrates SERS (Surface Enhanced Raman Spectroscopy) with newly fabricated nanocomposites.
• This method highlights the potential for real-time environmental testing, paving the way for future product applications.
