Abstract

Water is one of the essential requirements for human life. Various types of impurities that are present in the drinking water can produce grave health concerns, affect body tissues, and may lead to death. Protozoan parasites are one of the major biological pollutants in the water, which are ordinarily transferred across during the oral-fecal path. Cryptosporidium parvum oocysts (CPO) and Giardia lamblia (GL) are two frequently observed waterborne protozoan organisms. They have different values of index of refraction (IOR). Novel detector can be established with real-time detection based on this biophysical consideration. Here, an optical surface plasmon resonance biosensor (OSPRB) is developed for discovery of CPO and GL in drinking water. Angular examination and Kretschmann design are employed to explain the conception of the setup. An angular sensitivity (AS) of 188 Deg./RIU is attained by the suggested OSPRB with very low limit of detection (LOD) of 2.64 × 10⁻⁵ RIU. Other functioning factors are calculated for offered OSPRB. The achieved outcomes indicate that the suggested OSPRB has conspicuously improved performance as contrasted to aforementioned outcomes in the literatures. The suggested OSPRB can accelerate a substantial biological detecting tool with accurate and fast sensing at early point.

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
