Cortisol is a stress biomarker whose chronic elevated levels are associated with higher risk
of metabolic syndromes, anxiety, and cardiovascular diseases, among other medical …

Measuring cortisol levels as a stress biomarker is essential in many medical conditions
associated with a high risk of metabolic syndromes such as anxiety and cardiovascular …

This paper presents the development and feasibility tests of a cortisol immunosensor. The
sensor is based on surface plasmon resonance (SPR) using an unclad plastic optical fiber …

In this study, a localized surface plasmon resonance (LSPR)-based S-flex fiber optic (SFFO)
sensor is designed and developed for the qualitative as well as quantitative measurement of …

Gold-coated fiber Bragg gratings (FBGs) are nowadays a mature technology for lab-on-fiber
sensing based on surface plasmon resonance (SPR) excitation. Tilted FBGs bring valuable …

This paper reports on high-accuracy simulation of a grating structure based fiber optic
plasmonic sensor for salivary cortisol sensing. Gratings of SiO2 and SiC (one at a time) in …

In the biomedical detection context, plasmonic tilted fiber Bragg gratings (TFBGs) have been
demonstrated to be a very accurate and sensitive sensing tool, especially well-adapted for …

Surface plasmon resonance (SPR) optical fiber biosensors can be used as a cost-effective
and relatively simple-to-implement alternative to well established bulky prism configurations …

Introduction: Optical biosensors, particularly those based on nanoplasmonics technology,
have emerged in recent decades as a potential solution for disease diagnostics and therapy …

Optical fiber gratings have widely proven their applicability in biosensing, especially when
they are coupled with antibodies for specific antigen recognition. While this is customarily …
