Abstract:

An enormous development is experimented on the porous materials. The porosity was considered a defect in solid materials some years ago, but right now, this defect is an advantage, based on the properties obtained from micro, meso and macroporous materials, and their possible applications on a medical field. The feasibility to use forming agents to control the density and size of the pores, and the possibility to improve the porous properties through adding functional groups or nanoparticles on the porous surface allow the application of porous materials in many areas, especially on medicine. The Porous materials could be made with the use of organic compounds that can act as templates or pore-forming agents, through a versatile non-surfactant route in which nonsurfactant organic compounds such D-glucose, D-maltose, ascorbic acid, etc. Microporous, Mesoporous and Macro porous materials can be manufactured using many substances such as carbon, silicates, ceramics, minerals and polymers (silicone). Attached to the advantage of the porous materials, micro, meso and macro channels can be coated with metallic nanoparticles to further improve their biocompatibility properties. The surface modifications for polymers like Porous Silicon Matrix by applying coatings, or by using metal nanoparticles, increase the biocompatibility properties, prevent a nanofilms formation and favor interaction of living cells with the porous material, especially for its beneficial effect on cell adhesion and proliferation. Along with the control size porosity, the application of metal helps allow vascularization and the growth of cells inside. The silver and gold nanoparticles immobilized over the porous silicone matrix can be controlled to form a uniform film or a porous film, both options could be used for a medical application with a tremendous potential.
