Abstract Designing Photonic Crystal Fibers incorporating the Surface Plasmon Resonance Phenomenon (PCF-SPR) has led to numerous interesting applications. This investigation presents an exceptionally responsive surface plasmon resonance sensor, seamlessly integrated into a dual-core photonic crystal fiber, specifically designed for low refractive index (RI) detection. The integration of plasmonic material, namely silver (Ag), externally deposited on fiber structure, facilitates real-time...
In order to ensure the optimal functionality of biosensor devices across a diverse range applications, it is crucial accurately predict their detection times. This study delves into an in- depth exploration centrifugal and Coriolis effects that emerge due angular alignment radial displacement rotating microfluidic specifically designed for detecting complex reactive proteins (CRPs). To address this challenge, we introduce innovative hybrid model known as PSO-ANN, which combines power...
Binding reaction kinetics of analyte-ligand at the level a sensitive membrane into microchannel biosensor has been limited by formation boundary diffusion layer. Therefore, response time increases and affects overall performance biosensor.

The numerical simulation effect on binding performed using finite-element method. influence several parameters provided, such as average velocity at inlet microchannel...
Abstract Microfluidic biosensors offer a promising solution for real-time analysis of coronaviruses with minimal sample volumes. This study optimizes biochip the rapid detection SARS-CoV-2 using Taguchi orthogonal table L 9 (3 4 ), which comprises nine groups experiments varying four key parameters: Reynolds number (Re), Damköhler (Da), Schmidt (Sc), and dimensionless position reaction surface (X). Signal-to-noise (S/N) ratios variance (ANOVA) are employed to determine optimal parameters...
In this paper, we present a contribution to the development of fiber-optic surface plasmon resonance sensor coated with silver film that is suitable for chemical and biological applications. Indeed, importance choice metal deposited on sensitive zone was verified. It has been found silver-based sensors have better sensitivity.

In this work, we simulate the binding reaction of C-reactive protein in a microchannel biosensor. A problem that arises device concerns transport analyte toward surface biosensor, which is very small dimension. The limitation mass causes formation diffusion boundary layer and restrains whole kinetic reaction. To enhance performance biosensor by improving transport, an applied AC electric field flow confinement are used to stir field. numerical simulation these mechanisms on performed using...
