Breakthrough H₂O₂ Detection Eliminates Autofluorescence Interference

Researchers develop persistent luminescence nanoparticle probe for hydrogen peroxide detection that eliminates autofluorescence interference. Enables naked-eye visualization and instrument-free monitoring in food and consumer products.

This development matters because hydrogen peroxide residues in food, consumer products, and environmental samples pose significant health risks, including gastrointestinal irritation and potential cancer concerns. Traditional detection methods require specialized equipment and suffer from interference issues, limiting their practical application in real-world settings. This new technology enables rapid, sensitive detection without laboratory instruments, making it accessible for food safety monitoring in remote areas, quality control in manufacturing facilities, and environmental testing where resources are limited. By providing a reliable method to detect harmful H₂O₂ levels quickly and accurately, this innovation directly supports public health protection and product safety assurance across multiple industries.
