Researchers from the University of Illinois Urbana-Champaign have developed organic-material-based nanozymes – synthetic nanomaterials that have enzyme-like catalytic properties – that are non-toxic, environmentally friendly, and cost effective. To create these nanozymes, the researchers used a novel particle synthesis technique that brought each nanozyme’s size down to less than 100 nanometers. In one study, the researchers showed that these nanozymes, combined with a colorimetric sensing platform, could detect the presence of histamine in spinach and eggplant. In another study, the nanozymes were used to detect the presence of glyphosate, a common agricultural herbicide, in plants. “We were able to show that our system doesn’t just work in the lab, it has the potential to be utilized for real-world applications as a cost-effective molecule sensing system for food and agriculture,” said Dong Hoon Lee, lead author of the study.
