The work described herein has explored solid-phase transduction of nucleic acid hybridization on platforms composed of paper substrates, and also glass surfaces within glass/polydimethylsiloxane microfluidic channels. Single-stranded probe oligonucleotides were conjugated to qua…
The environmental, microbiological and technological aspects of selenium is explored with the aim of assessing and identifying microorganisms capable of interacting with Se in the environment and forming functional 'bionanomaterials'. To determine the natural microbial response …
Nano-emitters are the new generation of laser devices. A photonic-crystal cavity, which highly confines light in small volumes, in combination with quantum-dots can enhance the efficiency and lower the threshold of this device. The practical realisation of a reliable, electrical…
Quantum dots (QDs) are a semiconductor nanostructure in which a small island of one type of semiconductor material is contained within a larger bulk of a different one. These structure are interesting for a wide range of applications, including highly efficient LASERs, high-dens…
In recent years, interest has grown in the research fields of semiconductor lasers and photonic crystals. This thesis looks at integrating photonic crystals into existing semiconductor laser technology to act as functional laser mirrors. The majority of the research is conducted…
