For this purpose, intelligent therapeutics or ‘‘smart drug delivery’’ call for the design of the next generation of responsive devices and materials, bothfrompurelysyntheticmaterialsaswellasthroughcombinationofnatural and biological molecules with synthetic materials. In other advanced pharmaceutical applications, biomimetic materials, 05 especially polymeric networks, capable of biological recognition can be 0 FP prepared by designing interactions between the building blocks of biocom- 0- 0 patible networks and the desired specific ligands and by stabilizing these 8 6 3 interactionsbyathree-dimensionalstructure.Inaddition,biomimeticmethods 7 9 4 are now used to build biohybrid systems or even biomimetic materials 8 81 (mimicking biological recognition) for drug targeting and tissue engineering 7 9/9 devices.Additionally,micro-andnanofabricationtechniqueshaveenabledthe 3 0 developmentofnovelbiomedicalsystems,sensorsanddeliverydevicesthatcan 1 10. improve the therapeutic effect of drugs, such as micro- and nanoscale needles, doi: pumps, valves, and implantable drug delivery devices.

The book incorporates educational and research components with emphasis on the synthesis, design, development and analysis of novel structures useful in the biomedical, biochemical, cellular and related fields. Nanostructuredmaterialshavethuscreatedgreatexcitementinresearchand industrial circles because of numerous and diverse applications in electronic devices, automobile engines, industrial catalysts, and cosmetics. To date, and despite their great promise, applications of nanophase materials in the biomedical field (other than in drug delivery) have been close to nonexistent.
