The International Nanotechnology Olympiad (INO 2025) will take place online on September 28, 2025, allowing high school students worldwide to explore nanotechnology. Participants from various countries, including Iran, the U.S., and Germany, will engage in two phases: a Fundamental Concepts Assessment, which accounts for 70% of the score, and an Idea Generation and Film Submission phase, contributing 30%. Iran, a leader in nanotechnology education and research, has promoted this field since 2010, attracting over 113,667 students and achieving significant advancements in scientific publications and product sales. The INO 2025 aims to inspire innovative solutions to global challenges using nanotechnology.
