John A. Ugelstad

John A. Ugelstad was a Norwegian scientist renowned for developing a method to produce uniform, hollow microspheres—tiny, spherical particles—through a specialized manufacturing process. These microbeads have diverse applications, including in medicine for drug delivery, in research, and in industry. His innovation enabled precise control of particle size and structure, revolutionizing materials used in various technological fields. Ugelstad’s contribution has had a lasting impact on science and industry, advancing how we create and utilize microscopic materials for practical uses.
