Macroporous morphology

Fig. 9.10 SEM micrographs showing the dependence of macropore morphology on n-type doping density (2.5% HF, 5 mA cm 2, 2 V).

An additional porous polymer is poly(glycidyl methacrylate-ethyleneglycol dimethacrylate) (see Figure 2.46) that is synthesized by suspension polymerization in the presence of an inert porogen in the polymerization reaction, obtaining a material with an internal macroporous morphology characterized by an interconnected pore network, which permeates the extensively cross-linked polymer matrix [209],...

Relatively stable gels were formed for matrices loaded with approximately 6 mM whether provided by microspheres only in vitro or by a combination of ions from the reservoir microspheres and surrounding tissue fluid in vivo. Cellular inflltration of the gels was supported by the macroporous morphology of gels formed in sim following injection. The ability to incorporate soluble immunomodulatory factors like interleukin-2 (IL-2) directly into the matrix and the use of microspheres as modular components for slow release CpG oligonucleotides electrostatic anchored to the surface may provide a potent platform for immunotherapy when combined with delivery of immime cells [146]. 

Cell assemblies. As macroporous templates, these provide a facile bioinspired method for the synthesis of hierarchical macro-mesoporous titania with tunable macroporous morphology and enhanced photocatalytic activity [134]. This is also a simple and facile technique that can be used to prepare many types of metal oxide porous materials with good control over the pore size and morphology.

Macroporous silicon layers, with micron diameter pores, can be subjected to many standard processes developed by the microelectronics industry for silicon wafers, but these processes require tuning and optimization. A variety of processing techniques to manipulate macropore morphology, chemical composition, and patterning are reviewed.
