Sensitive and rapid detection of melamine in coffee powder by beta-cyclodextrin copolymer coated with silver nanoparticles by paper based Analytical-SERS technique

Key Points

• Melamine was detected sensitively in coffee powder, showcasing the effectiveness of the method.
• The technique uses beta-cyclodextrin coated with silver nanoparticles to enhance sensitivity.
• A paper-based Surface-Enhanced Raman Scattering (SERS) approach was utilized, leading to rapid results.
• This method may enable better food safety monitoring but requires further validation for practical application.
