Multi-channel SPR biosensor based on PCF for multi-analyte sensing applications [PDF]

open access: yes, 2015
This paper presents a theoretical investigation of a novel holey fiber (Photonic Crystal Fiber (PCF)) multi-channel biosensor based on surface plasmon resonance (SPR).

Plasmon resonance studies of iron coated gold films with and without an applied magnetic field

open access: yesAIP Advances, 2017
Surface plasmon excitations can result from the absorption of light incident on gold films. Adding a ferromagnetic metal, in our case iron, allows the surface plasmon resonance peak energy to be manipulated not only by the free electrons present in ...

Study of Immobilization Procedure on Silver Nanolayers and Detection of Estrone with Diverged Beam Surface Plasmon Resonance (SPR) Imaging

open access: yes, 2013
An immobilization protocol was developed to attach receptors on smooth silver thin films. Dense and packed 11-mercaptoundecanoic acid (11-MUA) was used to avoid uncontrolled sulfidization and harmful oxidation of silver nanolayers.

Critique of optical negative refraction superlensing [PDF]

open access: yes, 2011
Has the ten-year old quest for the optical superlens, based on Veselago’s hypothesis of negative refraction, been a chimera? We argue that Pendry’s alternative prescription of the silver superlens is nothing more than an application of the natural ...

Fv antibodies to aflatoxin B1 derived from a pre-immunized antibody phage display library system [PDF]

open access: yes, 2002
The production and characterization of recombinant antibodies to aflatoxin B[SUB1] (AFB[SUB1]), a potent mycotoxin and carcinogen is described. The antibody fragments produced were then applied for use in a surface plasmon resonance-based biosensor ...

Imaging surface plasmon resonance for multiplex microassay sensing of mycotoxins

open access: yes, 2011
A prototype imaging surface plasmon resonance-based multiplex microimmunoassay for mycotoxins is described. A microarray of mycotoxin–protein conjugates was fabricated using a continuous flow microspotter device.

Au-Graphene Hybrid Plasmonic Nanostructure Sensor Based on Intensity Shift

open access: yesSensors, 2017
Integrating plasmonic materials, like gold with a two-dimensional material (e.g., graphene) enhances the light-material interaction and, hence, plasmonic properties of the metallic nanostructure.

DNA-based biosensor platforms for the detection of TP53 mutation [PDF]

open access: yes, 2012
A DNA-based assay for the detection of one-point mutation in TP53 gene, responsible for lung cancer, was developed using a surface plasmon resonance (SPR) and a quartz crystal microbalance (QCM) biosensor systems.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

open access: yesAdvanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Improved Magneto-Optic Surface Plasmon Resonance Biosensors

open access: yesPhotonics, 2018
The magneto-optic (MO) characteristics and sensing performance of noble metal (Ag, Au, Cu) or transition metal (Fe, Ni, Co) single layers and Ag/Co or Au/Co bilayers have been studied and compared in both the standard plasmonic and MO plasmonic ...
