Light-Induced Self-Assembly of Ag NPs for Dual-Range Colorimetric Detection of Ethanol

Key Points

• This research aims to develop a simple sensor for rapidly detecting ethanol levels in beverages using silver nanoparticles (Ag NPs).
• Developed a colorimetric sensor employing light-triggered self-assembly of Ag NPs.
• Modulated sensor response based on the presence of ethanol.
• Evaluated sensor effectiveness for different ethanol concentrations.
• The sensor effectively detects ethanol across multiple concentration ranges.
• Demonstrated a clear color change corresponding to varying ethanol levels.
• Indicates potential for use in quality control in the beverage industry.
