Illustration of protocells coated with enzymes

Tunable chemotaxis of enzyme-coated protocells could lead to precision drug deliver. Illustration of protocells, called liposomes, that have enzymes (green) attached to their external surface moving through a microfluidic device. Depending on the enzyme, protocells can be made to move toward or away from gradients of chemical signals (grey dots).
