Recently, researchers have developed a new strategy for curcumin-based smart fluorescence anti-counterfeiting. This new strategy could be an effective tool to help reduce counterfeiting and protect consumers from fraudulent products. The new strategy uses curcumin, a naturally occurring pigment found in turmeric, to produce a “smart fluorescence” that is unique to each product. The fluorescence is generated when a product is exposed to ultraviolet light, and can be used to verify the authenticity of the product. This new method is simple and cost effective, and could be a powerful tool for combatting counterfeiting.
