The tiny beads added to some cleansers and cosmetics are one source of the long-lasting microplastics that threaten the environment. But MIT researchers have found a way to address the problem at its source: replacing them with polymers that break down into harmless sugars and amino acids. Particles of this polymer could also be used to encapsulate nutrients such as vitamin A to fortify foods, which could help some of the 2 billion people around the world who suffer from nutrient deficiencies. To develop the material, graduate student Linzixuan (Rhoda) Zhang and her colleagues turned to poly-beta-amino esters, a class of polymers previously developed in the lab of Institute Professor Robert Langer, ScD ’74, which have…
