Pulse Oximetry Imaging System Using Spatially Uniform Dual Wavelength Illumination
Abstract : Pulse oximetry is a non-invasive method for measuring blood oxygen saturation. However, its detection scheme heavily relies on single-point measurements. If the oxygen saturation is measured at a single location, the measurements are influenced by the profile of illumination, spatial variations in blood flow, and skin pigment. To overcome these issues, imaging systems that measure the distribution of oxygen saturation have been demonstrated.

Sensitivity enhancement of a silver based surface plasmon resonance sensor via an optimizing graphene-dielectric composite structure
Abstract A silver based surface plasmon resonance (SPR) sensor with dielectric-graphene composite film is presented. The influences of the dielectric layer and graphene on sensitivity and other sensing properties are theoretically calculated and then comprehensively discussed. The refractive index sensitivities for composite silver film based SPR sensors with graphene and dielectric layers could be increased by 29% and 288% more than that of monolayer silver film based SPR sensors, respectively.
Theoretical approach for modeling LSPR biosensors for the detection of biopolymer nucleation
Abstract We investigate theoretically the accuracy of an effective medium approximation in modeling localized surface plasmon resonance biosensors for the detection of biopolymer nucleation.
Theoretical Study on Gold Nanorod-Enhanced Near-Infrared Neural Stimulation
Over the past decade, optical methods have emerged for modulating brain functions as an alternative to electrical stimulations. Among various optical techniques, infrared neural stimulation (INS) has been effective via a thermal mechanism enabling focused and noninvasive stimulation without any genetic manipulation, but it results in bulk heating of neural tissue.
