Sirish Subash is no ordinary ninth-grade student. The 14-year-old from Gwinnett School of Mathematics, Science, and Technology in Snellville, Georgia, was named America's top young scientist after winning the 2024 3M Young Scientist Challenge. The reason? Subash's creation of an AI handheld pesticide detector named "Pestiscand." "It works on a method called spectrophotometry. Now what this means is that it uses different ways that light interacts with different chemicals to look for different chemicals on the produce," Subash [said]. "Each chemical reflects different parts or wavelengths of light, and that creates a spectral signature, which is basically a catalog of what wavelengths are reflected back. So, "Pestiscand" can look for those wavelengths that are reflected by side residues on the produce." While the product is not on the market for the broader public at this time, Subash aims to dedicate his time to ensuring it has mass availability in the near future. "I want to continue developing projects like "Pestiscand" and eventually get them out to the world, to the market. That's one of my goals for "Pestiscand", to get it out to everyone," Subash added. In his downtime, Subash enjoys reading both fiction and non-fiction and making origami. His $25,000 prizefund will go toward his college education
