Highly sensitive optical fibre long period grating biosensor anchored with silica core gold shell nanoparticles

Marques, L.; Hernandez, F. U.; James, Stephen W.; Morgan, S. P.; Clark, M.; Tatam, Ralph P.; Korposh, Sergiy (Elsevier, 2015-08-22)

An optical fibre long period grating (LPG), modified with a coating of silica core gold shell (SiO2:Au) nanoparticles (NPs) deposited using the layer-by-layer method, was employed for the development of a biosensor. The ...
Novel highly sensitive protein sensors based on tapered optical fibres modified with Au-based nanocoatings

Urrutia, Aitor; Bojan, Kartheka; Marques, L.; Mullaney, Kevin; Goicoechea, Javier; James, Stephen W.; Clark, M.; Tatam, Ralph P.; Korposh, Sergiy (Hindawi Publishing Corporation, 2016-08-08)

In this work, novel protein sensors based on tapered optical fibres modified with Au coatings deposited using two different procedures are proposed. Au based coatings are deposited onto a non-adiabatic tapered optical fibre ...
Sensitive protein detection using an optical fibre long period grating sensor anchored with silica core gold shell nanoparticles

Marques, L.; Hernandez, F. U.; Korposh, Sergiy; Clark, M.; Morgan, S. P.; James, Stephen W.; Tatam, Ralph P. (SPIE, 2014-12-31)

An optical fibre long period grating (LPG), modified with a coating of silica gold (SiO2:Au) core/shell nanoparticles (NPs) deposited using the layer-by-layer (LbL) method, was employed for the development of a bio-sensor. ...
