Synthetic proteins have been created that move in response to their environment in predictable and tunable ways. These motile molecules were designed from scratch on computers, then produced inside living cells.
Synthetic proteins have now been created that can move in response to their environment in predictable and tunable ways. These proteins can use their movement to disrupt lipid membranes in cells. They show promise as tools for drug delivery, and might eventually rival the efficiency of virus vehicles, but without some of their drawbacks.
