Abstract Jute ( Corchorus sp.) is one of the most important sources of natural fibre, covering ∼80% of global bast fibre production 1 . Only Corchorus olitorius and Corchorus capsularis are commercially cultivated, though there are more than 100 Corchorus species 2 in the Malvaceae family. Here we d...

A novel, perfectly hexagonal lattice photonic crystal fiber (PCF) biosensor based on surface plasmon resonance (SPR) is proposed in this research. To design and investigate the influence of several initial geometric parameters on the sensing properties of the sensor, finite element method (FEM) base...

We proffer in this research a distinctive, facile to fabricate, and highly sensitive photonic crystal fiber (PCF) biosensor based on the phenomenon of surface plasmon resonance (SPR). Our prototype has a strategic pattern of circular air holes inside the fiber, which leads to a superior sensing perf...

We propose a novel design of a slotted core photonic crystal fiber (PCF) that offers ultra low-loss and high birefringence attribute for efficient transmission of terahertz (THz) waves. A finite element method has been used to investigate the modal characteristics of the PCF. Our design incorporates...

BACKGROUND: The lack of appropriate prognostic biomarkers remains a significant obstacle in the early detection of Head and Neck Squamous Cell Carcinoma (HNSCC), a cancer type with a high mortality rate. Despite considerable advancements in treatment, the success in diagnosing HNSCC at an early stag...
