“Organic nanozymes enable detection of histamine in spinach and eggplant, and glyphosate and glucose in various samples.”
In the heart of Illinois, a groundbreaking revolution is taking place in the realm of sustainable agriculture and food safety. We’re witnessing the dawn of a new era where organic nanozymes are transforming the way we approach agricultural sensing and food safety detection. This innovative research introduces a cutting-edge generation of environmentally friendly nanomaterials that possess remarkable enzyme-like catalytic properties. Let’s delve into this exciting development and explore how it’s set to change the landscape of agriculture and food safety.
The Rise of Organic Nanozymes in Agricultural Sensing
Nanozymes, synthetic materials with enzyme-like catalytic properties, have long been utilized in biomedical applications, particularly for disease diagnostics. However, conventional inorganic nanozymes have faced limitations in agricultural and food industry applications due to their toxicity, high costs, and complex production processes. This is where our groundbreaking research at the University of Illinois Urbana-Champaign comes into play.
Our team has successfully developed organic-material-based nanozymes that address these challenges head-on. These novel nanozymes are non-toxic, environmentally friendly, and cost-effective, making them ideal for use in agricultural and food safety applications. But what exactly sets these organic nanozymes apart from their inorganic counterparts?
- Enhanced stability
- Smaller particle size
- Improved performance
- Biodegradability
- Sustainability
These characteristics make organic nanozymes a game-changer in the field of molecule detection for agricultural and food products.
The Evolution of Organic Nanozymes
The journey to develop these revolutionary organic nanozymes was not without its challenges. As lead author Dong Hoon Lee, who completed his Ph.D. from the Department of Agricultural and Biological Engineering (ABE) at the University of Illinois, explains:
“The first generation of organic-compound-based (OC) nanozymes had some minor drawbacks. They required the use of particle stabilizing polymers with repeatable functional groups, which assured stability of the nanozyme’s nanoscale framework but didn’t achieve a sufficiently small particle size.”
To overcome these limitations, our research group implemented several key improvements:
- Utilization of a core amino acid (L-alanine) and polyethylene glycol as constituent materials
- Development of a novel particle synthesis technique
- Reduction of particle size to less than 100 nanometers
These advancements resulted in nanozymes that closely resemble the physical framework and mimic the catalytic activity of target enzymes, opening up new possibilities for agricultural and food safety applications.
Colorimetric Sensing Platform for Rapid Detection
One of the most exciting aspects of our research is the development of a colorimetric sensing platform that works in tandem with the organic nanozymes. This innovative system enables rapid, on-site detection of various molecules in agricultural and food products.
“Smartphone-based agricultural testing using organic nanozymes offers rapid, cost-effective analysis for on-site food safety checks.”
In our first study, we demonstrated that the organic (OA) nanozymes, when combined with this colorimetric sensing platform, could successfully detect the presence of histamine in food products. We focused on spinach and eggplant, which are among the vegetables with the highest concentrations of histamine.
The results were impressive:
- Affordable analytic performance profile
- Potential for real-world applications
- Cost-effective molecule sensing system for food and agriculture
This breakthrough has significant implications for food safety testing, allowing for rapid, on-site detection of potentially harmful compounds in our food supply.
Point-of-Use Platform for Agricultural and Biological Molecule Detection
Building on the success of our initial research, we further refined the organic (OM) nanozyme production process and developed an integrated, colorimetric point-of-use platform. This system enables rapid detection of agricultural and biological molecules without the need for a laboratory environment.
As Lee explains, “Conventional detection methods are based on laboratory analysis, but it would be helpful to have a portable molecule sensing system for the agricultural and food environment, similar to point-of-care systems such as in-home COVID tests.”
Our team applied this system to detect two important compounds:
- Glyphosate: A common agricultural herbicide
- Glucose: A ubiquitous biological molecule
In both cases, our system demonstrated excellent analytic sensitivity, providing accurate results within minutes. This rapid turnaround time is crucial for on-site testing and decision-making in agricultural settings.
Smartphone Integration for User-Friendly Testing
One of the most innovative aspects of our research is the integration of smartphone technology with the OM-nanozyme-based colorimetric sensing platform. This combination creates a truly portable and user-friendly solution for on-site testing.
Here’s how it works:
- Users add food samples to a liquid solution
- The sample is tested with a small paper microfluidic strip
- If catalytic activity occurs, the strip changes color to green
- The color intensity indicates the potential presence of the target molecule
- Users take a picture with their smartphone
- A specialized app uses an algorithm to convert the color image to an estimated concentration of target molecules
This seamless integration of nanotechnology, synthetic biology, and mobile applications creates a powerful tool for farmers, food safety inspectors, and consumers alike.
