What if you could detect toxic plasticizers in plastics within seconds, just by looking? 👀
Commonly used in products such as food packaging and toys, toxic plasticizers can migrate from plastics undetected, potentially leading to serious health implications. Existing testing methods can be costly and complex, while current colorimetric sensors often require immersion and produce only temporary color changes.
University of Florida researchers have developed low-cost chromogenic photonic crystal sensors that produce a permanent color change when exposed to migrating plasticizers. The sensors detect contaminants at solid-solid interfaces within seconds, providing a visual readout visible to the naked eye or a smartphone camera.
This simple, rapid method offers a scalable solution for quality control, regulatory compliance, environmental monitoring, and product safety testing.
