Shape of the Gold Nanostructures Versus Etching Time
To check the process of wet etching, 500 nm diameter silica nanospheres were deposited with 50 nm of gold at the angle of 70 ° and slowly wet etched at a 10 times diluted potassium iodide gold e[r]

The binding interaction between the proteins and the nanoholes on the gold nanoisland surface caused distint shifts in the LSPR peak, as detected by UV-visible absorption spectrometry. Figure 1B shows the chip- based detection system and representativ[r]

The previous section has shown that potential induced defects may occur within the SAM. This naturally leads to a discussion on methods which can study defect formation and behavior in a SAM film. In this section we discuss there methods of interest for detection in alkanethiol f[r]

CHAPTER 1: INTRODUCTION
Research background
Surface plasmon resonance (SPR) phenomenon describes the oscillation of free electron cloud on the surface under electromagnetic wave of light. For optical biosensors, some researchers have develope[r]

In a SAW device, IDT patterns can be considered as a periodic structure. When an acoustic wave propagates on the surface through the periodic structure, it is partially reflected at each IDT finger. Depending on the operating frequency of the acoustic wave, the reflected part[r]

It is important to note that the complete disappear- ance of the Au-CO band for samples with a concen- tration below 65% Au does not necessarily imply the absence of Au on the surface of the nanoparticles; it implies rather the preferential Pt-atop CO adsorption over Au-atop CO adsorpt[r]

NaCl, 20 m m Tris ⁄ HCl, pH 8.5, 1 m m EDTA) and freeze– thawed six times. The resulting multilamellar vesicles were converted to SUV by sonication (MSE 150 W ultrasonic disintegrator, MSE, Butte, UT) of the suspension at room temperature. The SUV suspension was centrifuged at 12 000 g for 15[r]

With polymer blends containing compatibilizer, when the EVOH content increased from 10-30%, the component polymers had good dispersion and compatibility with each other.[r]
