At just 14 years old, Sheyna Patel has created an innovative gel that can capture and destroy more than 93% of microplastics in water. These tiny fragments of plastic—impossible to see with the naked eye—pose a growing threat to oceans and marine biodiversity. Her invention acts like a sponge, trapping and removing the particles, and offering a tangible solution to one of today’s most urgent environmental problems.
Mentorship that shaped an idea
Sheyna didn’t do it alone. She collaborated with Deborah Isabelle, a product engineering specialist at 3M, who guided her through setbacks and encouraged her to believe in the feasibility of her vision. “Her mentorship helped me push past obstacles and believe more in my ability to actually make this happen,” Sheyna explained. That guidance allowed her to refine the idea into a working prototype—safe, functional, and now ready to be tested in real-world conditions.
Finalist at the 3m young scientist challenge 2025
Her gel has already brought her to the finals of the 2025 3M Young Scientist Challenge, an international competition that celebrates students aged 11 to 14 who propose scientific solutions to everyday problems. Contestants are judged on their creativity, scientific knowledge, and communication skills.
As part of the challenge, students spend the summer in a mentorship program with 3M scientists, sharpening their projects before heading to the company’s Innovation Center in St. Paul, Minnesota. There, in October, finalists will present their ideas before a panel of experts.
More than just science
Sheyna’s work doesn’t simply tackle microplastics—it illustrates how young minds can play a crucial role in environmental protection. Past winners of the competition have developed devices to detect pesticides, conserve water, and monitor air pollution. Their projects, while born from classrooms and kitchen tables, have carried real-world impact.
The 3M Young Scientist Challenge continues to inspire students to approach science with creativity and purpose, channeling their STEM skills into solutions that matter. Many alumni have gone on to TED Talks, patents, Forbes 30 Under 30 recognition, and television appearances—proof that even the youngest innovators can help shape the planet’s future.
