Recent Advancement of Nanomaterials: Properties, Fabrication, and Applications

Nanotechnology has revolutionized materials science, enabling the development of nanoparticles, nanocomposites and nanomaterials with superior mechanical, electrical, optical and thermal properties for applications in medicine, electronics, energy and environmental sustainability.The data were taken from recent publications available via Scopus, Web of Science and Google Scholar.This review examines their classification, synthesis methods, key properties and applications and highlights the role of metal, metal oxide, carbon-based, polymeric and quantum dot nanoparticles in biomedicine, catalysis and nanoelectronics.Synthesis techniques are categorized into top-down (ball milling, lithography, laser ablation) and bottom-up approaches (sol-gel, chemical vapor deposition, biological synthesis), each offering unique advantages in terms of scalability and precision.Nanocomposites, including polymer-based, metal-based and ceramic-based types, incorporate nanofillers to improve mechanical strength, thermal stability and electrical conductivity, using fabrication methods such as in-situ polymerization.Functionalization further expands their applications in drug delivery, flexible electronics, and advanced coatings.However, challenges related to toxicity, environmental impact, scalability, and regulations persist, necessitating sustainable synthesis, AI-driven material design, and stringent ethical standards.Addressing these issues is key to unlocking nanotechnology's full potential for next-generation industrial and scientific advancements.
