Researchers at Princeton’s Department of Chemistry discovered the first known de novo protein that catalyzes, or drives, the synthesis of quantum dots. Nature uses 20 canonical amino acids as building blocks to make proteins, combining their sequences to create complex molecules that perform biol
Professor Michael Hecht and his research group at Princeton have made a significant discovery in the field of chemistry by creating the first known de novo protein that catalyzes the synthesis of quantum dots. Quantum dots are nanocrystals with fluorescent properties that are used in a range of electronic applications, including LED screens and solar panels.
Their work opens the door to making nanomaterials in a more sustainable way by demonstrating that protein sequences not derived from nature can be used to synthesize functional materials — with pronounced benefits to the environment. “So here, we’re making novel proteins that never arose in life doing things that don’t exist in life.”
