A feasibility study of a leaky waveguide aptasensor for thrombin (2019)
Journal Article
Alamrani, N. A., Greenway, G. M., Pamme, N., Goddard, N. J., & Gupta, R. (2019). A feasibility study of a leaky waveguide aptasensor for thrombin. Analyst, 144(20), 6048-6054. https://doi.org/10.1039/c9an01421g

This proof-of-principle study demonstrates the feasibility of a leaky waveguide (LW) aptasensor, where aptamers were immobilised in a mesoporous chitosan waveguiding film for the detection of thrombin. This work has demonstrated that aptamers immobil... Read More about A feasibility study of a leaky waveguide aptasensor for thrombin.

A method for determining average iron content of ferritin by measuring its optical dispersion (2019)
Journal Article
Gupta, R., Alamrani, N. A., Greenway, G. M., Pamme, N., & Goddard, N. J. (2019). A method for determining average iron content of ferritin by measuring its optical dispersion. Analytical chemistry, 91(11), 7366-7372. https://doi.org/10.1021/acs.analchem.9b01231

© 2019 American Chemical Society. We report a method where the refractive index increments of an iron storage protein, ferritin, and apoferritin (ferritin minus iron) were measured over the wavelength range of 450-678 nm to determine the average iron...

Purcell enhancement and focusing effects in plasmonic nanoantenna arrays (2015)
Journal Article
Stokes, J. L., Sarua, A., Pugh, J. R., Dorh, N., Munns, J. W., Bassindale, P. G., …Cryan, M. J. (2015). Purcell enhancement and focusing effects in plasmonic nanoantenna arrays. Journal of the Optical Society of America B, 32(10), 2158-2163. https://doi.org/10.1364/JOSAB.32.002158

This paper presents measured fluorescence results for PMMA dye-coated 5×5 gold plasmonic nanoantenna arrays. We use numerical electromagnetic modeling to show how array size and element spacing can be used to control emitted beam shape and compare th...

Solar absorbers using 1D and 2D periodic nanostructured nickel films (2014)
Journal Article
Ahmad, N., Stokes, J., & Cryan, M. J. (2014). Solar absorbers using 1D and 2D periodic nanostructured nickel films. Journal of Optics, 16(12), Article 125003. https://doi.org/10.1088/2040-8978/16/12/125003

This paper presents results obtained from finite difference time domain and transfer matrix method modelling of nickel thin films. It is shown that by adding a periodic 1D grating to the surface of the nickel its optical absorption over the 300 nm–10...
