This presentation discusses the design and synthesis of nanostructured materials and films with multifunctional responsive surfaces. The electronic, optical, and dielectric properties of various nanostructured films have been widely investigated. More recently, there has been a growing interest in these materials for health and biomedical applications. Two key areas of research have been pursued: (1) the formation of the nanostructures themselves on a multilength scale, and (2) the incorporation of the recognition and responsive properties. On a molecular level, techniques such as molecular imprinting have been explored. On the nano- and sub micrometer length scale, self-assembly and super-molecular templating have attracted wide attention. On the micro- and macrolength scale, micro machining and lithography have been extensively used. In addition, novel synthesis methods have been developed to incorporate active sites and functionalities so that the nanostructured hosts can selectively recognize, or even respond to the change of the environment. For molecular recognition, selective ligands, or size-and-shape selective cage structures, are introduced. For responsive properties, environmental sensitive polymers, or other switchable organic molecules, are investigated. The challenge is to integrate the nanostructured materials and the functionalities on different length scales so that the whole material will have the proper chemical and physical properties, and will detect and respond to the change in the environment. Many examples from our own research, as well as from other groups, will be given to illustrate the potential of the integrated approaches.
