Development and optimisation of patterned optical immunosensors [PDF]

open access: yes, 2005
This work describes the successful design, fabrication and implementation of a generic, optimised immunosensor. The first stage of the work was the establishment of the techniques required to develop an effective immunosensor, in particular, antibody ...

Real Time Dual-Channel Multiplex SERS Ultradetection [PDF]

open access: yes, 2013
Surface-enhanced Raman scattering (SERS) can be combined with microfluidics for rapid multiplex analyte screening. Through combination of the high intensity and complex signals provided by SERS with the flow characteristics of microfluidic channels, we ...

Fluorescence and surface-enhanced vibrational spectroscopies of lawsone and plumbagin

open access: yesSpectroscopy Letters, 2016
The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and surface-enhanced IR absorption. From the absorption spectrum, it was possible to infer that the enol-lawsone tautomer concentration decreases in silver colloidal solution. Plumbagin dimers,

Plasmonic Sensor and Surface Enhanced Fluorescence Imaging Based on Hollow Nanocone Arrays

open access: yesChemosensors, 2022
Hollow nanocone arrays are fabricated by a low-cost and efficient colloidal lithography (CL) technique. The hollow nanocone arrays are then reversed to make only the tips contact the substrate.

A 3D Plasmonic Crossed-Wire Nanostructure for Surface-Enhanced Raman Scattering and Plasmon-Enhanced Fluorescence Detection

open access: yesMolecules, 2021
In this manuscript, silver nanowire 3D random crossed-wire woodpile (3D-RCW) nanostructures were designed and prepared. The 3D-RCW provides rich “antenna” and “hot spot” effects that are responsive for surface-enhanced Raman scattering (SERS) effects and
