Two great goals of biomolecular science are to monitor biomolecular interactions in real time and with sufficient sensitivity to allow small amounts of biological material to be investigated. The achievement of these goals is limited by the methods of transducing these reactions. The aim of this multidisciplinary proposal is to overcome this limitation by developing photonic devices that exploit the unique properties of nanoporous silicon. The hybridisation of DNA will be used as a model biorecognition reaction. Potential applications of these photonic devices are as highly sensitive affinity sensors and as tools for investigating the kinetics of biomolecular interactions.Read moreRead less

Better vibrations: controlling light with sound in semiconductor chips. Combining new concepts in the theory of nonlinear optics with advanced experiments, this project aims to develop smart waveguides that bind sound and light tightly together. Laser light and sound waves seem worlds apart, but in the right conditions we can make them interact: sound can change the colour of light. Harnessing this control of light in tiny waveguides on semiconductor chips would enable the development of unique ....Better vibrations: controlling light with sound in semiconductor chips. Combining new concepts in the theory of nonlinear optics with advanced experiments, this project aims to develop smart waveguides that bind sound and light tightly together. Laser light and sound waves seem worlds apart, but in the right conditions we can make them interact: sound can change the colour of light. Harnessing this control of light in tiny waveguides on semiconductor chips would enable the development of unique and useful optical devices, but trapping sound in chips is tremendously difficult. By exploiting untapped material properties, the project seeks to break limits on the freedom and strength of interactions between light and sound. Project outcomes may establish a new class of optical chips for optical sensing and analysis in fields from security to communications to the biosciences.Read moreRead less
