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 [...]
