Tunable antifouling behaviour on rough surfaces. The impact of subtle variations in nano and micro scale surface roughness on larger scale wetting and antifouling behaviour of surfaces is investigated. This will lead to next generation non-toxic coatings for both medical and marine applications. The environmental implications will be a significant feature of the ongoing assessment of this study.

Summary
Shape sorting of nanoparticles at oil-water interfaces in microchannels. This project aims to study the effect of shape on the adsorption of nanoparticles at an oil/water interface and develop a rapid, inexpensive, efficient, versatile method for shape sorting of nanoparticles using a microfluidic approach. This technique can be applied for fractionation of synthetic nanoparticles, biosample analysis and environmental monitoring.

Single-Molecule Circuitry for Nanoscale Electronic Devices. The aim of this project is to develop novel methods for forming robust single-molecule circuitry. The use of single molecules in electronics represents the next level of miniaturisation of electronic components, which would enable us to meet the expanding demands of modern technologies and to continue the downscaling trend in electronic devices.

The aim of this project is to develop novel methods for forming robust single-molecule circuitry. The use of single molecules in electronics represents the next level of miniaturisation of electronic components, which would enable us to meet the expanding demands of modern technologies and to continue the downscaling trend in electronic devices. This project aims to address the requirements needed to translate single-molecule electronics from its current status as a fundamental tool to real-world applications. Key approaches will be the use of surface chemistry to develop new methods of wiring single molecules and the integration of robust single-molecule junctions with semiconducting electrodes. The expected project outcomes pave the way for single-molecule electronic and analytical devices.Read moreRead less

Illuminating drug activity in the brain with nanocrystalline beacons. The project focuses on developing technologies to understand the activity of drugs and precisely locate their target sites in the brain. Novel nanocrystalline beacons and ultrahigh-sensitivity optical imaging technology developed in the project have the aim to help visualise opioid and other related drug molecules over extended periods, which is impossible with current methods.

The project focuses on developing technologies to understand the activity of drugs and precisely locate their target sites in the brain. Novel nanocrystalline beacons and ultrahigh-sensitivity optical imaging technology developed in the project have the aim to help visualise opioid and other related drug molecules over extended periods, which is impossible with current methods. Quantifying drug target distribution in the brain and imaging their dynamics on a single molecule level will shed light on drug-target interactions.Read moreRead less
Patchy colloidosomes at interfaces: correlation of particle surface heterogeneity, wettability, and chemical activity at the nanoscale. The surfaces of natural mineral particles are made up of spots with such different chemical and physical properties. The complexity makes it hard to predict their behaviour. This project will provide insights into how the 'patchy' nature of particle surfaces affects their behaviour in processes such as flotation separation and bio-fuel production.

Controlling Defects in 2D Materials for Advanced Optoelectronics. Control over defect densities in 2D transition metal chalcogenide films permit controlled fabrication of van der Waals heterostructures and other ultra-thin electronic devices. This is crucial for controlling the optoelectronic properties of devices, yet, unlike bulk semiconductors, defect and dopant control in 2D transition metal chalcogenides is not presently possible.

Control over defect densities in 2D transition metal chalcogenide films permit controlled fabrication of van der Waals heterostructures and other ultra-thin electronic devices. This is crucial for controlling the optoelectronic properties of devices, yet, unlike bulk semiconductors, defect and dopant control in 2D transition metal chalcogenides is not presently possible. This project aims to investigate the optical properties of single-defects, and how to control them using sensitive microscopy and controlled ligand deposition. Simultaneous electronic characterisation and single-defect microscopy in fabricated thin-film transistors will be investigated to correlate optical and electronic properties of thin-film devices.Read moreRead less

The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety. This project aims to develop new methodological and conceptual avenues to close the gap between innovation in nanotechnology and risk assessment. This is intended to be achieved by developing and validating high-throughput in vitro toxicity screening platforms for manufactured nanoparticles. The approach is based on advanced lab-on-a-chip microfluidic technologies. The predictive power of the platform will be refined and optimised via ex-vivo and in-vivo models.Read moreRead less
Geometry variation and coupling of single gold nanorods for highly efficient, one-photon and two-photon luminescent markers. The search for highly efficient, non toxic and stable luminescence markers is continuing for many applications in bio- and nano-photonics. The project's study of gold nanorod luminescence is designed to fundamentally understand and control the luminescence quantum efficiency of gold nanorod and ultimately unveil its potential as the future marker.
