Abstract:
PURPOSE: A gold nanoparticle-purine complex is provided to show stability in cells or in vivo, to safely deliver a drug, and to release purine-based compounds at a desired time. CONSTITUTION: A gold nanoparticle-purine complex is provided. A purine compound is 6-mercaptopurine or 6-thioguanine. A drug delivery system has the gold nanoparticle-purine complex and glutathione. In the drug delivery system, the purine-based compounds are released from the gold nanoparticle-purine complex by treating the gold nanoparticle-purine complex with glutathione.
Abstract:
PURPOSE: A fluorescence and SERS detection method of Hg(II) concentration on gold nanocolloid surface is provided to detect Hg ion of low concentration. CONSTITUTION: A method for measuring Hg(II) concentration of an aqueous solution comprises: a step of binding an organic fluorescence dye and obtaining SERS spectrum of the organic fluorescence dye; a step of adding Hg(II) in the aqueous solution to the gold nanoparticles and obtaining SERS spectrum of the organic fluorescence dye; and a step of comparing two SERS spectrum intensity. The organic fluorescence dye is rhodamine 6G or rhodamine 123.

Abstract:
PURPOSE: A method for detecting the thermal stability of a self-assembled thin film in a ruthenium dye-sensitive solar cell is provided to offer a useful base for manufacture of a ruthenium dye-sensitive solar cell. CONSTITUTION: A method for detecting the thermal stability of a self-assembled thin film in a ruthenium dye-sensitive solar cell detects changes in infrared spectrum according to changes in the temperature of NCS or CN group included in ruthenium dye. The infrared spectrum is obtained by DRIFT(Diffuse Reflectance Infrared Fourier Transform) spectroscopy, and the ruthenium dye is selected from the group consisting of N719((Bu4N)2[Ru(dcbpyH)2-(NCS)2) N3 and ruthenium 505.
