We would like to offer big congratulations to the students from NIST International School in Bangkok who have been recognised for their innovative solution at the 2022 Diamond Challenge, a global entrepreneurship competition for high school students. The team, led by Mix, Setsiri Chaiyosburana, was awarded ‘The Global Innovation Prize,’ one of the only two such prizes awarded to the 700 teams from 37 countries and 28 states who competed in the competition.
The team presented NANO-L, an anti-pathogenic coating that incorporates silver nanoparticles to effectively eliminate pathogens. What sets NANO-L apart from other anti-pathogenic coatings is the environmentally friendly production process it employs. Sugarcane leaves are used to create silver nanoparticles, which were inspired by Setsiri Chaiyosburana's trips to visit his grandparents in Kanchanaburi, where he witnessed sugarcane fields emitting plumes of black smoke during the burning season.
NANO-L's remarkable achievements go beyond the Diamond Challenge Global Innovation Prize, as it also received acclaim in other international competitions such as the iCAN competition in Canada, and the WICO and Inventions Geneva competitions. Setsiri hopes that the accolades they have received will inspire more opportunities for Thai youth inventors to showcase their practical and innovative ideas.
