Abstract: A complex matrix made of a thin film of an inorganic oxide and a manufacturing method thereof are provided to offer superior adhesive force between the inorganic oxide of thin film and a silicon wafer by forming a single layer of the inorganic oxide of thin film or a multilayer of the thin film. A manufacturing method for a complex matrix made of a thin film of an inorganic oxide comprises the following steps of: performing a sintering process after performing a first electric radiation process of a sol for radiating on a surface of a silicon water; forming an inorganic oxide thin film on the water; and performing the sintering process after performing a second electric radiation process of a sol different with the first used sol on the inorganic oxide thin film formed on a surface of another silicon wafer repeatedly. The inorganic oxide contained in the inorganic oxide thin film is one selected from a particle or fiber of which diameter is 1,000nm or less.

Abstract: Carbon nano tube-chitosan composite formed by covalent bonding is provided to noticeably improve bio-compatibility and solvent dispersion capability, thereby being advantageously applied to gene delivery system, by endowing acidic property to carbon nano tube through amide bond of amine compound and covalently bonding the nano tube to chitosan to produce the composite. The process of forming the composite includes the steps of: (i) incorporating carboxylic group to carbon nano-tube by mixing nitric acid and carbon nano-tube then carrying out reflux of the mixture; (ii) substituting the incorporated carboxylic group with -COCl group by filtering the obtained carbon nano tube, washing the tube with distilled water to have pH7, drying the treated tube, adding SOCl2 to the tube and refluxing the treated tube; (iii) preparing carbon nano tube-chitosan composite by filtering the nano tube with incorporation of -COCl group, washing the tube with anhydrous CH2Cl2, drying the treated tube, adding acetic acid containing dissolved chitosan to the tube and refuxing the treated mixture; and (iv) removing unreacted chitosan by washing the composite with acetic acid, filtering and washing the composite with distilled water to have pH7.

Abstract: A method for preparing a hydroxyl-apatite nano-complex is provided to generate nano-scaled crystals within the hydroxyl-apatite nano-complex, thereby increasing the surface area of the nano-complex and decrease the reduction of strength of the nano-complex. A gold nanoparticle solution stabilized with N-acylated chitosan is prepared by mixing and stirring HAuCL4 solution and an N-acylated chitosan solution for 1-2 hours and then adding NaBH4 into the mixed substance. A product in which hydroxyapatite is crystallized on gold nanoparticles is produced by aging the gold nanoparticle solution for 1-2 hours while adding a CaCl2 solution into the gold nanoparticle solution, and then aging the aged substance for 1-3 hours while adding NaHPQ into the aged substance.
