A new study has revealed how perovskite-modified surfaces can detect food contamination under visible light. The study, published in the journal Advanced Materials, found that perovskite nanocrystals on surfaces were highly responsive to food contaminants such as bacteria, viruses, and toxins. The study could have implications for food safety and help to reduce foodborne illness.

Perovskite-modified surfaces have the potential to revolutionize food safety. The nanocrystals are extremely sensitive to contaminants, and the detection can be done under visible light. This means food safety tests no longer need to take place in a laboratory. The nanocrystals are also non-toxic, meaning they are safe to use in food production. The study could pave the way for more efficient and cost-effective food safety tests.
