A review on the implications of nanoparticles and their association with radiation and industries

Nanoparticles are particles between 1 and 100 nm, flaunting distinctive chemical, physical, and mechanical properties that are incredibly different from their bulk equivalents. However, a high surface area to volume ratio makes them highly reactive and robust, albeit with tunable optical properties, which is leading to revolutionary applications in engineering, energy, and life sciences. Essentially, the analysis examines two consequential implications of nanoparticles: their combination with basic fluids to create nanofluids for improved thermal management, and their joint exploitation with radiation, as well as in food science. The dispersion of nanoparticles into conventional fluids dramatically adapts their thermophysical properties, such as viscosity and thermal conductivity, particularly to accomplish nanofluids as superior coolants in industrial systems. Furthermore, nanoparticles also serve as adequate agents in medical radiation therapy, as well as solar energy absorption. In the food industry, they are crucial in enhancing safety, packaging, and preservation through antimicrobial activity, contaminant detection, and nutrient encapsulation. This effort synthesizes the latest furtherances in these domains, accentuating the synthesis, properties, and multifaceted applications of nanoparticles while also addressing related challenges and future research directions.
