Model-based image analysis of a tethered Brownian fibre for shear stress sensing (2017)
Journal Article
Gallagher, M. T., Neal, C. V., Arkill, K. P., & Smith, D. J. (2017). Model-based image analysis of a tethered Brownian fibre for shear stress sensing. Interface, 14(137), doi:10.1098/rsif.2017.0564. ISSN 1742-5662

The measurement of fluid dynamic shear stress acting on a biologically relevant surface is a challenging problem, particularly in the complex environment of, for example, the vasculature. While an experimental method for the direct detection of wall... Read More

A high resolution study of dynamic changes of Ce2O3 and CeO2 nanoparticles in complex environmental media (2017)
Journal Article
Merrifield, R. C., Arkill, K. P., Palmer, R. E., & Lead, J. R. (2017). A high resolution study of dynamic changes of Ce2O3 and CeO2 nanoparticles in complex environmental media. Environmental Science and Technology, 51(14), doi:10.1021/acs.est.7b01130. ISSN 0013-936X

Ceria nanoparticles (NPs) rapidly and easily cycle between Ce(III) and Ce(IV) oxidation states, making them prime candidates for commercial and other applications. Increased commercial use has resulted in increased discharge to the environment and in... Read More

Direct detection and measurement of wall shear stress using a filamentous bio-nanoparticle (2015)
Journal Article
Lobo, D. P., Wemyss, A. M., Smith, D. J., Straube, A., Betteridge, K. B., Salmon, A. H., …Arkill, K. P. (2015). Direct detection and measurement of wall shear stress using a filamentous bio-nanoparticle. Nano Research, 8(10), doi:10.1007/s12274-015-0831-x. ISSN 1998-0124

The wall shear stress (WSS) that a moving fluid exerts on a surface affects many processes including those relating to vascular function. WSS plays an important role in normal physiology (e.g. angiogenesis) and affects the microvasculature's primary... Read More
