Approaches to surface-functionalised materials for biomedical applications

Pitt D.W., Treharne A., Grossel M.C., University of Southampton, UK
There are many types of retinal disease which vary widely, with some being easier to treat than others. One such example is Age-Related Macular Degeneration (AMD) which is the largest cause of blindness for those [...]

Germanium antimony sulphide nano wires fabricated by chemical vapour deposition and e-beam lithography

Huang C-C, Tai C-Y, Liu C-J, Simpson R.E., Knight K., Hewak D.W., University of Southampton, UK
Germanium antimony sulphide (Ge-Sb-S) amorphous thin films and nano wires have been directly deposited and patterned on SiO2-on-silicon substrates by means of chemical vapour deposition, e-beam lithography and dry etching. The Ge-Sb-S thin films were [...]

Nanoparticle optical memory function

Soares B.F., Bashevoy M.V., MacDonald K.F., Jonsson F., Zheludev N.I., University of Southampton, UK
Light and electron-beam induced structural transformations in nanoparticles of polymorphic metals provide a paradigm for achieving resonator-less optical memory functionality with picojoule energy requirements. We demonstrate optical memory function with gallium nanoparticles grown by light-assisted [...]

Optical and impedance detection of DNA hybridisation on barcoded micro particles in a microfluidic device

Holmes D., Whitton A., Cavalli-Petraglia G., Galitonov G., Birtwell S., Banu S., Zheludev N., Morgan H., University of Southampton, UK
A common problem with high throughput combinatorial chemistry is the inability to easily analyse and track the multitude of molecules produced. This bottleneck is a major problem for the big pharmaceutical companies and other researchers [...]

High Capacity Nano-optical Diffraction Bar-code Tagging for Biological and Chemical Applications

Banu S., Birtwell S., Chen Y., Galitonov G., Morgan H., Zheludev N., University of Southampton, UK
Here we describe a new method for encoding small beads which allows for non-contact reading. The tagging technique is based on fabricating a nano-structured pattern on the surface of the particle, which is only a [...]

Design Optimisation of an Electrostatic MEMS Actuator with Low Spring Constant for an “Atom Chip”

Rouabah H.A., Gollasch C.O., Kraft M., University of Southampton, UK
The advance of MEMS based sensors and microfabrication techniques has facilitated innovative technologies such as so-called ‘atom chips’, where a cloud of ultra cold atoms in a Bose Einstein Condensate (BEC) is controlled and manipulated [...]

An Algorithmic Approach to the Optimal Extraction of Signals from Intelligent Sensors

Boltryk P.J., Harris C.J., White N.M., University of Southampton, UK
This paper describes current research into the development of an intelligent sensor architecture, where signal conditioning is performed onboard the sensor itself, in software. Our proposed architecture for an intelligent sensor uses data-based models of [...]

Information Controlled Wireless Sensor Networks with Energy Aware Nodes

Merrett G., Al-Hashimi B.M., White N.M., Harris N.R., University of Southampton, UK
We propose an algorithm whereby each node in a WSN decides its network involvement independently of its neighbouring nodes, based on its own resources and the information contained in the message. The concept of our [...]

Numerical Modelling of a Microfluidic Ultrasonic Particle Separator

Townsend R.J., Hill M., Harris N.R., White N.M., Beeby S.P., University of Southampton, UK
Particles held in a fluid suspension and within an acoustic standing wave experience an acoustic radiation force. The force causes particles to move to the pressure nodes of the acoustic field creating a concentrate, contributing [...]

Simulation of Micromachined Inertial Sensors with Higher-Order Single Loop Sigma-Delta Modulators

Dong Y., Kraft M., University of Southampton, UK
Micromachined capacitive inertial sensors incorporated in sigma-delta force-feedback loops have been proven to improve linearity, dynamic range and bandwidth, and also provide a direct digital output. Previous work mainly focused on using only the sensing [...]
