Abstract:

The objectives of the work presented were to 1) fabricate reproducible nanorod array SERS substrates, 2) detection of bacteria using nanorod substrates, 3) detection of DNA hybridization using nanorod substrates and 4) critically evaluate the sensing method. Important findings from this work are as follows. A novel method for batch fabrication of substrates for surface enhanced Raman scattering (SERS) has been developed using a modified platen machined to fit in a commercial electron beam evaporator. The use of this holder enables simultaneous deposition of silver nanorod (AgNR) arrays on

Abstract:

The aim of the present work is the study and the nanofabrication of innovative plasmonic nanostructured materials to develop label-free optical biosensors. The motivation arises from the need to identify specific biological molecules at very low concentrations (below the picoMolar level) and with high specificity. This goal is of paramount importance for instance in diagnostics and prognostics through the early-stage detection of markers in biological fluids indicating possible altered biological processes. At the same time a fast and simple detection scheme is required, without the use of l

Abstract:

This dissertation describes the development of a new method for increasing the resolution of the current protein microarray technology, down to the single molecule detection level. By using a technique called size-dependent self-assembly, different proteins can be bound to different sized fluorescent nanostructures, and then located on a patterned silicon substrate based on the sized pattern which is closest to the size of the bead diameter.The protein nanoarray was used to detect antibody-antigen binding, specifically anti-mouse IgG binding to mouse IgG.

Arrays of nanotubes/rods made of appropriate materials can yield unique radiative properties, such as large absorption and optical anisotropy, with broad applications from high-efficiency emitters and absorbers for energy conversion to the polarization conversion via anisotropic responses. The objective of this dissertation is to investigate the radiative properties of arrays formed by aligned carbon nanotubes (CNTs) and silver nanorods (AgNRs).

The optical and magneto-optical response of plasmonic resonances in metallic nanoarrays out of square structures, either in holes or islands, were investigated. The excitation of the Bragg Plasmons takes place within a grating. Significant differences in the excited plasmon modes were seen by using p- or s-polarized light as well between the holes and islands sample. In order to investigate magneto-optical response from the magnetic nanostrucures, transverse magneto-optical Kerr effect (TMOKE) measurements were done with the result that there is a difference in holes and islands sample.

Complementary metal-oxide semiconductor (CMOS) technology has driven the electronic scenario for the last 40 years. The exponential grow of computing power implicates technological challenges, such as scaling transistor sizes, increasing clock frequency and reducing the power consumption. These goals raise dramatically the manufacturing cost with every new technology node. The projections of the ITRS roadmap report tell us that the scaling will be also influenced by fundamental physical limits.

These nanoarrays are 80 nm in width and 500 nm-1 μm in length. We use standard electron-beam lithography to fabricate two Ti/Au electrodes with a gap of 250-350 nm. The ac electric fields, inducing movement of polarizable nanoarrays, are applied to deposit the nanoarrays into the nanoscale gap.
