Introduction Surface Plasmon Resonance (SPR) sensors stand at the forefront of label-free biosensing technologies, relying on the excitation of surface plasmons—coherent electron oscillations—at metal-dielectric interfaces. The resonance condition, and hence the sensor’s response, is acutely sensitive to changes in the local refractive index, making SPR particularly valuable in the detection of biomolecules, chemicals, and environmental […]
Introduction Photonic crystal fiber (PCF)-based gas cells (PCF Sensor) have emerged as an indispensable component in optical gas sensing, particularly in Raman and absorption-based techniques. These gas cells offer significant improvements over traditional sensing architectures by enhancing light-gas interaction length, enabling miniaturization, and offering higher sensitivity and selectivity. The structure of PCFs, characterized by microscopic […]
Introduction Workflow automation is undergoing a profound transformation as businesses and professionals shift toward local AI tools. In 2025, the emphasis is not merely on automating repetitive tasks but doing so with heightened attention to privacy, speed, and control. The traditional reliance on cloud-based solutions is being reconsidered, especially by sectors dealing with sensitive data […]
Introduction Photonic Crystal Fibers (PCFs) represent one of the most fascinating advancements in fiber optics over the past few decades. Unlike traditional optical fibers that rely solely on core-cladding refractive index differences to guide light, PCFs employ a highly structured arrangement of microscopic air holes running along their length. These microstructures form a periodic dielectric […]
Introduction Writing a master’s thesis represents one of the most intellectually demanding yet personally rewarding phases in a student’s academic life. It stands as both a test of mastery in a chosen field and a bridge between student inquiry and professional research. A thesis is not simply an extended essay—it is a structured, original investigation […]
Introduction Complex permittivity, denoted as $\varepsilon = \varepsilon’ – j\varepsilon”$, plays a central role in the understanding and simulation of electromagnetic and optical materials. Here, $\varepsilon’$ refers to the dielectric constant that quantifies a material’s ability to store electric energy, while $\varepsilon”$ captures the loss or dissipation of energy within the material. This dual nature […]
Introduction The intersection of microfluidics and surface plasmon resonance (SPR) has become a pivotal frontier in the development of real-world, deployable diagnostic tools, especially for point-of-care (POC) applications. SPR, a label-free biosensing technology that detects changes in the refractive index near a sensor surface, when combined with the precision fluid control offered by microfluidics, opens […]
Introduction Surface plasmon-based sensing platforms have become indispensable tools in biosensing, pharmaceutical development, and environmental diagnostics. Among these, Surface Plasmon Resonance (SPR), Localized Surface Plasmon Resonance (LSPR), and Surface Plasmon Resonance Imaging (SPRi) represent the most widely applied technologies in the field of plasmonics. Each approach has distinct physical principles, detection strategies, and performance parameters […]
Introduction Terahertz (THz) waves occupy the frequency range between microwave and infrared bands, typically spanning from 0.1 to 10 THz. Often dubbed as the “terahertz gap” due to historical challenges in generating and detecting radiation within this range, recent years have seen a rapid resurgence of interest in THz technologies. This renewed focus is largely […]
Introduction The intersection of artificial intelligence and materials science has emerged as one of the most transformative frontiers in modern research and engineering. At the heart of this convergence lies a simple but powerful question: Can AI design better materials than humans? As industries ranging from renewable energy to biomedical devices grapple with the growing […]
