Summary
Miniaturised fibre-optic probes for biomedical image and sensor data fusion. The project aims to develop new types of tiny biomedical imaging devices based on optical fibres that can be inserted into the body via hypodermic needles or catheters. These devices will have the ability to generate a three-dimensional image of the tissue region. As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. ....Miniaturised fibre-optic probes for biomedical image and sensor data fusion. The project aims to develop new types of tiny biomedical imaging devices based on optical fibres that can be inserted into the body via hypodermic needles or catheters. These devices will have the ability to generate a three-dimensional image of the tissue region. As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. These minimally invasive devices will produce information-rich multidimensional fused image and sensor data, opening up new possibilities for biologists and medical researchers to study disease progression and treatment in living animals and humans, with great potential for scientific discovery.Read moreRead less
Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded ....Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded nano-Radiators (SUPER) Dots), based on purpose-engineered up-conversion nanocrystals that are ultra-bright and have low background interference, high specificity, speed, and large-scale multiplexing capacity. These probes will allow microscopy and flow cytometry to measure hitherto undetectable rare-event molecules and cells, opening new frontiers for the discovery of new biomarkers.Read moreRead less
Rapid detection of rare-event cells by strong UP-conversion
encoded nano-radiators (SUPER Dots): finding a needle in a haystack. Current diagnostic tests are not sensitive enough to detect cancer in its very early stages or early recurrence following treatment. The new technologies developed by this project will be able to find single cancer cells in blood and urine samples heralding a new era in medical diagnostics.
Engineering the Next Generation of Terahertz Laser Imaging Systems. This project aims to develop terahertz imaging systems based on quantum cascade lasers suitable for characterisation of skin, with major implications for early skin cancer detection. Despite advances in treatment regimes, the most significant predictor of skin cancer survivability remains early detection.

This project aims to develop terahertz imaging systems based on quantum cascade lasers suitable for characterisation of skin, with major implications for early skin cancer detection. Despite advances in treatment regimes, the most significant predictor of skin cancer survivability remains early detection. The project’s approach uses the semiconductor laser in the optical-feedback interferometer configuration, and is designed to afford significant advantages over conventional terahertz imaging platforms. The project plans to explore new semiconductor physics of a quantum cascade laser under optical feedback, engineer the semiconductor laser-based platform for medical diagnostic applications, and develop supporting numerical techniques.Read moreRead less

This project aims to make the fluoride glass fibre platform the preferred material for generating ultrashort pulses at 2.8 nm and beyond. High power and efficiency from simple device architectures are essential for industry, medicine and defence. Modern sources of short pulses of light emitting mid-infrared wavelengths are complicated and inefficient. This project will improve fibre sources emitting short pulses and create the essential building blocks for future all-fibre arrangements that will be more robust. The sources are expected to have applications in non-linear optics and materials modification.Read moreRead less
