Traditional methods of viral detection are based on the isolation and culture of viral pathogens, but often viruses cannot be cultivated under laboratory conditions, constituting a substantial barrier to viral diagnostics and discovery. Microfluidics is a multidisciplinary field in which low volumes of fluids are used in high-throughput screening. Therefore, when combined with appropriate system and filter designs, microfluidics could make the ideal technology for the filtering, detection and quantification of viruses within a sample. This proposal is an integral part of a one year pump- prime project to analyse the properties of viruses which differ substantially in size, shape & deformability on different microfluidic surfaces. This information from neutron reflectivity and scattering will be used to inform mathematical modelling leading to initial trial microfluidic devices.
