Surface immobilization of biomolecules by light

Development of immunosensors based on commercially available surface acoustic wave (SAW) devices

“…Here, however, gold structures are lacking and coating of the device with a thin gold film has not proved advantageous. Therefore, photoimmobilization [35] has been applied for the immobilization of the dextran layer on the coated SAW surface. This promising new method will be discussed more detailed in the following.…”

Simultaneous amination of TiO2nanoparticles in the gas phase synthesis for bio-medical applications

“…In particular, amination is known as a typical surface modification method and deeply related to the linkage between surface and target biomolecules such as antibodies, antigen, enzymes, RNA, and DNA [5][6]. Moreover, there have been many reports on the application of amino groups attached to various surfaces to biosensors, patterning, biological modeling and sensing, and coatings, etc [5][6][7].…”

“…In this sense, a simultaneous synthesis and surface amination process providing biological activity, concentrated on the inorganic nanoparticles, is proposed in the present study. In order to achieve these goals, the surface of TiO 2 nanoparticles synthesized through chemical vapor condensation (CVC) process was modified employing thermal decomposition of APTES (3-aminopropyltriethoxysilane, H 2 N(CH 2 ) 3 Si(OC 2 H 5 ) 3 ) as an surface modifier [7,[11][12].…”

Photophysical and photodecomposition studies on polyethylenes: A novel application of gas-phase mirage-effect spectroscopy

“…In general, an understanding of the physical and light (UV/vis) are termed as photochemical degand have been successfully used by several researchers for trace gas detection into the ppb and radation, and those involving light and oxygen, as photooxidation, and heat and oxygen, as therseveral tenth ppt (when intracavity detection is used) range. [7][8][9][10][11][12] The limitations imposed by use mooxidative degradation and/or decomposition/ combustion.…”
