Overview

Multimode detection platform demonstrates high sensitivity for copper ions using colorimetric and SERS techniques.

Key Points

  • Peptide-gold nanoparticles enabled highly sensitive sensing of copper ions, with picomolar sensitivity reported.
  • Significant visual colorimetric change was observed, shifting from colorless to light brown upon interaction with copper ions.
  • Optical spectroscopic techniques, including surface-enhanced Raman spectroscopy, were used to enhance detection capabilities.
  • The study presents a potential photodynamic therapy agent using gold nanoparticles for in vitro applications.
