Functional doubly porous materials based on polymer networks were engineered via novel porogen templating methodologies.  Straightforward and versatile strategies were implemented through the use of either CaCO3 microparticles or poly(methyl methacrylate) beads as macroporogens, in conjunction with either hydroxyapatite nanoparticles or a porogenic solvent (e.g., ethanol) as nanoporogens.  Upon porogen removal, macropores with dimensions in the 100 �m range were generated, while the second porosity lied within the 1 �m order of magnitude, as evidenced by mercury intrusion porosimetry and scanning electron microscopy.  The possibility to further biofunctionalize biporous cross-linked poly(2-hydroxyethyl methacrylate) (PHEMA)-based frameworks was investigated through a three-step synthetic approach involving an activation stage, followed by two coupling reactions. The success of the functionalization procedure was clearly demonstrated by Raman spectroscopy.
