Variable wavelength surface plasmon resonance (SPR) in biosensing

Biosystems, 2009
In this study, we fabricated a novel variable wavelength surface plasmon resonance (SPR) sensor, which detects resonance conditions such as a maximum attenuation wavelength, measuring change of microscopic refractive index. Such a change was measured to detect a salmonella antigen-antibody reaction and a penicillinase-penicillin reaction.

Gold-nanoshells as surface plasmon resonance (SPR)

SPIE Proceedings, 2015
Coreshell plasmonic nanoparticles (CS) are a class of nanoparticles that exhibit optical absorption in the near IR regime and have potential biomedical applications in imaging, therapy and sensing. We present our preliminary investigation on the applications of CS as a surface plasmon based sensor to study the functional properties of human blood.

Application of chromogenic reagents in surface plasmon resonance (SPR)

Biosensors and Bioelectronics, 2007
In this paper, a new simple approach for sensitivity optimization in surface plasmon resonance (SPR) chemosensors based on colorimetric ligands is presented. A new design of SPR sensor with tunable analytical wavelength (lambda(SPR)) was constructed for this purpose, to perform studies on the ligand absorbance spectra related sensitivity enhancement ...

Surface Plasmon Resonance (SPR) biosensor for detection of mycotoxins: A review

Journal of Immunological Methods, 2022
Mycotoxin is one of the most important natural pollutants, which poses a global threat to food safety. However, the pollution of mold in food production is inevitable. The detection technology of mycotoxins in food production is an important means to prevent the damage of mycotoxins, so rapid detection and screening to avoid pollution diffusion is ...

Electrochemical surface plasmon resonance (EC-SPR) aptasensor for ampicillin detection

Analytical and Bioanalytical Chemistry, 2019
Surface plasmon resonance technique is highly sensitive to various processes taking place on a metal film and it has emerged as a powerful label-free method to study molecular binding processes taking place on a surface. Another important but less explored area of applications is the use of hybrid methods which combine electrochemistry with optical ...
