dc.description.alternativeAbstractThis dissertation is related to applications for nanotechnology and biotechnology. In the concrete, this dissertation research is the fabrication and characterization of functionalized ultra thin film and nanostructures with functional dyes, such as hemicyanine dye, spirooxazine dye, and squarilym dye, diacetylene derivative, and biomaterials such as penicillinase and human immunoglobulin G for nanotechnology and biotechnology applications for example, molecular computer, molecular optical switch and memory, and biosensor. The dissertation was composed of 3 parts with 7 chapters, Part I is the introduction part and another parts were shown the research results. It can be divided into two parts according to the construction and characterization of molecular organic ultra-thin films with functional dyes and molecules in Chapter 2-5, while Chapter 6-7 are concentrated on the works with bio-molecules of enzymes as like as penicillinase and antibody-antigen as like as human immunoglobulin G. An outline of each chapter is as follows. Part Ⅰ is introduced the general background for understanding of the objects and published previous results in this dissertation. This part involves the introduction of each material, objects and published previous results of each research. Part Ⅱ is related to the fabrications and characterizations of functional dyes and molecules for nanotechnology applications. This part falls into four chapters as a kind of functionalized materials such as hemicyanine, spiroxazine, squrarilum dye, and diacetylene derivatives. Part Ⅲ was shown the constructions and characterizations of bio-materials for biotechnology applications. Enzymes and antigen-antibody were used for biomaterials such as penicillinase and human immunoglobulin G.-
