A template‐directed and surface‐modified method for the facile synthesis of polypyrrole (PPy) or polyaniline (PAni) hollow spheres having smooth surface, uniform wall thickness, and a range of controllable sizes is developed. The use of these biocompatible hollow spheres as a new class of contrast agents for sonography (see image) is also demonstrated.
