Ginkgo biloba leaf polysaccharide-modified Cu2-xSe nanozymes for smartphone-assisted colorimetric detection of food additive propyl gallate.
Propyl gallate (PG), a widely used synthetic phenolic antioxidant, has raised health concerns due to its potential risks from overexposure. Traditional methods such as chromatography are typically time-consuming, labor-intensive, and not suitable for on-site rapid screening. In this work, we successfully fabricated ult...
