Mercuric ion detection by plasmon-enhanced spectrophotometric ellipsometer using specific oligonucleotide probes
2020, Spectrochimica Acta - Part A: Molecular and Biomolecular SpectroscopyCitation Excerpt :Both the SPR and spectrophotometric ellipsometry can be used for the analysis and the characterization of ultra-thin films deposited on any reflective (but smooth) surfaces in physics, chemistry and biology fields. The incorporation of these techniques depends on the design of the appropriate sensor chip and immobilization techniques [31–33]. In SPR based sensor applications, the detection limit can be reduced to 10 nM oligonucleotide target [34].
Study on optimization of nano-coatings for ultra-sensitive biosensors based on long-period fiber grating
2020, Sensing and Bio-Sensing ResearchCitation Excerpt :The effect of MT with consideration of two different thin layers BFL and RL of different thickness) have been analyzed critically. The RI of BFL has been chosen to be 1.54 [13,18,19] and the RI of the receptor layer was chosen as 1.5 for the analysis as RI of the dry protein is in the range of 1.4–1.6 [41]. The thickness of the bio-functional layer is kept at 5 nm for the purpose of computations.

2012, Optics CommunicationsCitation Excerpt :Assuming the refractive indices of IgG and a-h-IgG to be identical without taking effective optical constants of a bilayer structure suggests that the optical characteristics can be described by a simple two-layer model, in which the resonance shifts obtained as a result of IgG/a-h-IgG interactions result from the change in the layer thicknesses [34]. The thicknesses of IgG and a-h-IgG layers were assumed to be 7 and 9 nm, respectively [35]. Also, effective refractive index of buffer was identical to that of water at 1.33.
Is biosensor a viable method for food allergen detection?
2001, Analytica Chimica ActaCitation Excerpt :The effect of cleaning is illustrated in Fig. 2, where the refractive index value for PBS was decreased after treatment with the cleaning solution. The cleaning treatment also rendered the film hydrophilic, which was important in reproducible adsorption of antibodies to the gold surface [16] and in minimal denaturing of the adsorbed antibodies [17]. The adsorption of peanut antibodies in PBS containing BSA to form an overlayer on the gold surface could be monitored in real-time as an increasing refractive index value.
