Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body. By coating the surface of the protocells with enzymes—proteins that catalyze chemical reactions—a team of researchers at Penn State was able to control the direction of the protocell’s movement in a chemical gradient in a microfluidic device. A paper describing the research appears November 18, 2019 in the journal Nature Nanotechnology.
