WASHINGTON, D.C. – Sirish Subash, a 14-year-old Indian-American student, has been crowned America’s Top Young Scientist for his groundbreaking invention – PestiSCAND, a portable device that detects dangerous pesticide residues on produce with remarkable accuracy. The teen innovator claimed the prestigious 2024 3M Young Scientist Challenge title and a $25,000 prize for his potentially life-saving creation.
How PestiSCAND Works: AI Meets Food Safety
The handheld device revolutionizes pesticide detection by combining:
- Optical sensor technology that scans produce surfaces
- Artificial intelligence algorithms trained on pesticide chemical signatures
- Instant results display showing contamination levels
With lab tests confirming 85%+ accuracy, the innovation could empower consumers to check fruits and vegetables at home or markets before purchase.

“Current detection methods require expensive lab equipment,” Sirish explained during his award presentation. “PestiSCAND makes food safety accessible to everyone.”
From Classroom to Global Impact
The young inventor’s journey began with alarming statistics:
WHO estimates 385 million pesticide poisonings annually
USDA reports show pesticide residues on 70%+ non-organic produce
Existing solutions cost thousands and require technical expertise
Sirish spent months developing and refining prototypes before achieving his breakthrough. His science teacher, Dr. Elena Rodriguez, noted, “What sets Sirish apart is his determination to solve real-world problems affecting ordinary families.”
Affordable Safety Coming Soon
With his prize money and 3M mentorship, Sirish plans to:
- Further refine detection accuracy to 90%+
- Launch consumer version priced at just ~$20
- Explore partnerships with grocery chains and food safety organizations
The device could prove particularly valuable in developing nations where pesticide regulation enforcement remains challenging.
A Bright Future Ahead
Sirish joins notable alumni of the competition whose inventions have gone on to save lives and disrupt industries. Judges praised his:
Practical application addressing critical health concerns
User-centric design prioritizing accessibility
Commercial viability with clear mass-market potential
“This proves age is no barrier to meaningful innovation,” said 3M Chief Science Advocate Dr. Jayshree Seth. “Sirish exemplifies how young minds can drive progress on global challenges.”
