Sumita Mitra's curiosity inspired a dental filling material from observing grape clusters. She developed nanoclusters, mimicking grapes for stronger, lifelike dental restorations. This innovation transformed teeth restoration over a decade of dedicated research. Mitra's groundbreaking work earned her induction into the National Inventors Hall of Fame. Her legacy continues to inspire future generations of scientists and inventors.
