Self-floating, self-water-supplying, recyclable cellulose SERS platform with Au@Ag nanocubes for food contaminant detection

Key Points

• Food contaminant detection achieved with a cellulose platform integrated with Au@Ag nanocubes, promoting safety.
• With a sensitivity of detection as low as 1 ppb, this method shows promise for real-world applications.
• Utilizing surface-enhanced Raman spectroscopy (SERS) allows for precise identification of harmful substances.
• Potential for eco-friendly and recyclable materials in food safety promotes sustainable practices.
