Polymeric nanostructured materials (PNMs), which are polymeric materials in nanoscale or polymer composites containing nanomaterials, have become increasingly useful for biomedical applications. In specific, advances in polymer-related nanoscience and nanotechnology have brought a revolutionary change to produce new biomaterials with tailored properties and functionalities for targeted biomedical applications. These materials, including micelles, polymersomes, nanoparticles, nanocapsules, nanogels, nanofibers, dendrimers and nanocomposites, have been widely used in drug delivery, gene therapy, bioimage, tissue engineering and regenerative medicine. This review presents a comprehensive overview on the various types of PNMs, their fabrication methods and biomedical applications, as well as the challenges in research and development of future PNMs. 相似文献

Recent technological advancements in polymeric buckypaper materials have brought spotlight on polymer/nanodiamond buckypaper. This review is designed as systematic and comprehensive source of information and research on nanodiamond, polymer/nanodiamond nanocomposite and buckypaper, and technological advancement in this field. Structure, properties, and manufacturing techniques of polymer/nanodiamond buckypaper are reviewed. Because of outstanding physical properties, polymer-based buckypaper has been used as potential contenders in nanofilter, supercapacitor, fuel cell, electrical components, and biomedical devices. However, property dependence in relation to chemical structure is not fully identified in the literature. To find out further technical suitability of polymer/nanodiamond materials are still among predominant research challenges. 相似文献
