Introduction Zeta potential, often denoted as ζ-potential, is the electrokinetic potential that develops at the slipping plane of a particle in a liquid medium. It quantifies the electrical potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle. In simple terms, it measures the degree of electrostatic repulsion […]
Introduction Surface plasmon resonance (SPR) sensors have emerged as a critical innovation in the landscape of food safety and quality control. Defined as a label-free, real-time optical biosensing technique, SPR functions by detecting refractive index changes near a sensor surface, typically a gold film, allowing precise identification of biomolecular interactions. Its relevance in food safety […]
Introduction Surface Plasmon Resonance Imaging (SPRI) has emerged as a pivotal label-free optical technique that enables real-time observation of biomolecular interactions and cellular dynamics. Unlike conventional fluorescence-based assays, SPRI relies on monitoring changes in the refractive index at a metal-dielectric interface—typically involving gold films—making it highly sensitive to surface-bound molecular events. This unique capability allows […]
Introduction In an increasingly data-intensive academic landscape, numerical simulation has become not only a methodological tool but also a core pillar of scientific discovery. Especially in the context of Q1 journals—those in the top quartile of their field by impact factor—simulation-driven research has seen exponential growth. High-impact journals now prioritize submissions with robust, validated, and […]
Introduction Surface Plasmon Resonance (SPR) is a resonant optical phenomenon arising at the interface between a dielectric and a metal, enabling the detection of minute changes in refractive index. Over the past few decades, SPR has become foundational to numerous sensing technologies, particularly in biosensing and chemical detection. The sensitivity and specificity of SPR sensors […]
Introduction Water is arguably the most vital resource on Earth, yet its contamination has escalated into a global concern that continues to challenge scientists, regulators, and industries alike. Emerging contaminants such as per- and polyfluoroalkyl substances (PFAS), microplastics, and a host of chemical pollutants now pervade freshwater systems, oceans, and even drinking water supplies. The […]
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 Solid-state batteries (SSBs) represent a major technological shift in energy storage, particularly when compared to conventional lithium-ion batteries. The fundamental difference lies in the replacement of the liquid electrolyte with a solid-state counterpart, which offers improved energy density, safety, and longevity. As demand grows in sectors like electric vehicles (EVs), consumer electronics, and renewable […]
Introduction The integration of artificial intelligence (AI) into the field of physics has emerged as one of the most promising and transformative developments in recent scientific history. No longer confined to optimizing experiments or crunching numbers, AI systems are now actively contributing to hypothesis generation, simulation, data interpretation, and even the formulation of physical laws.
