Abstract: A porous, molecularly imprinted polymer and a process for its preparation are described. The porous, molecularly imprinted polymer is characterised in that it is obtainable by providing a porous silica; attaching a molecular template to the surface of the porous silica; filling the pores of the porous silica with a polymer, removing the silica and the molecular template, thereby leaving a porous, molecularly imprinted polymer. The process is characterised by the above defined process steps. Also described are a porous polymer vesicle and its preparation with the same features as defined for the porous, molecularly imprinted polymer and its preparation, except for the lack of the molecular template and thus the lack of the molecular imprint in the porous polymer.

Abstract: A polymeric scaffold contains pendant liquid crystal side chains and has fully interconnected pores. Such a polymeric scaffold will preferably be 3D in nature and elastomeric, biocompatible and biodegradable. Such 3D liquid crystal elastomer (LCE) scaffolds can be used for various biomedical applications, including cell culture applications. A method for the production of such a polymeric scaffold containing liquid crystals and having interconnected pores is also disclosed that uses a metal foam sacrificial template as a scaffold to produce the polymeric smart response scaffold of the present invention. Consistent and controlled pore sizes result from etching the sacrificial metal foam template away from the polymeric scaffold, permitting the incorporation of growth factors, when needed, for enhancing cell viability and proliferation.

Abstract: Ordered, monodisperse macroporous polymers, their corresponding ordered, monodisperse colloids, and methods of preparing them are disclosed. The methods use an ordered, monodisperse colloidal template to define the polymer pore morphology, which in turn acts as a mold for the growth of a new ordered, monodisperse colloid. The macroporous polymer may be prepared with either spherical or ellipsoidal pores from a wide variety of polymeric systems. The new ordered, monodisperse colloid may be grown from a wide variety of materials including ceramics, semiconductors, metals and polymers. These materials are potentially useful in optical, micro-filtering and drug delivery applications.
