Single-hole hollow polymer microspheres (see Figure) have been synthesized through the direct polymerization and cross-linking reactions occurring at the surface of carboxyl-capping polystyrene colloids, followed by removal of the core particles. The molecular imprinting of these single-hole hollow microspheres towards the specific high-capacity uptake of target species opens new routes to promising applications.
