Nanoparticles Slideshare, Jan 8, 2025 · Learn about the unique physical and chemical properties of nanoparticles, their size-dependent characteristics, crystal structure, surface area-to-volume ratio, and examples of nanoparticles exhibiting unusual properties in various fields. Nanoparticles are sub-100nm colloidal structures that can be used as drug delivery systems. Nanoparticles are distinguished from microparticles (1–1000 μm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects [3] or electric properties. Their unique properties, stemming from their size and surface area, allow for innovative applications in medicine, environmental science, and materials engineering, among others. 4 days ago · A nanoparticle (or nanopowder or nanocluster or nanocrystal) is a microscopic particle with at least one dimension less than 100 nm. Their small size, up to 100 nm, and potential for surface modifications have enabled their use in a wide range of applications. Additionally, the May 21, 2026 · Nanoparticles are particles that exist on a nanometre scale (i.
