14-Year-Old Innovator Develops AI Device to Detect Pesticides on Produce
In late 2024, Sirish Subash, a 14-year-old from Snellville, Georgia, made a huge leap in food safety by winning the 3M Young Scientist Challenge. His creation, PestiSCAND, is a handheld, AI-powered device designed to detect pesticide residues on fruits and vegetables. Using spectrophotometry, PestiSCAND attaches to a smartphone and provides real-time analysis, allowing users to ensure their produce is free from harmful chemicals before consumption.
The device was rigorously tested on common produce such as tomatoes, spinach, apples, and strawberries, achieving an impressive accuracy rate of over 85%. This breakthrough innovation earned Subash the prestigious title of America’s Top Young Scientist and a prize of $25,000.
How PestiSCAND Works
PestiSCAND uses spectrophotometry, a scientific technique that measures how light interacts with the sample, allowing the device to detect pesticide residues at a molecular level. By connecting the device to a smartphone, users can easily scan produce to receive immediate feedback on the presence of pesticides.
The Importance of PestiSCAND
Pesticides are widely used in agriculture to protect crops from pests and diseases, but residues left on fruits and vegetables can pose significant health risks. Consumers are often unsure whether washing produce can effectively remove these harmful chemicals. PestiSCAND provides a solution to this problem by offering an easy, accessible way to check produce safety before consumption.
The device’s success underscores the potential for artificial intelligence and machine learning to address real-world problems. By empowering consumers with technology that can verify the safety of food, Sirish Subash's innovation paves the way for healthier living and greater confidence in the food supply chain.
The Future of PestiSCAND
With his success in the 3M Young Scientist Challenge, Sirish’s next steps include scaling the technology for home use and expanding its ability to detect a wider range of pesticides. The vision is to make PestiSCAND widely accessible, allowing households to monitor produce safety quickly and efficiently.
Sirish’s work is a shining example of how young minds, motivated by curiosity and care, can drive innovative solutions for public health and food safety.
