It is also explained as nanoparticles have a high surface to volume ratio. In a bulk semiconductor, for example, the electronic properties depend on the band gap between occupied electron levels and unoccupied electron levels. In 2008 the International Organization for Standardization (ISO) defined a nanoparticle as a discrete nano-object where all three Cartesian dimensions are less than 100 nm. Dr. Ananya Mandal is a doctor by profession, lecturer by vocation and a medical writer by passion. A substance that consists of nanoparticles is described as being nanoparticulate. This difference in properties is the result of two things: Nanoparticulate materials have many uses. For example, ferroelectric materials smaller than 10 nm can switch their magnetization direction using room temperature thermal energy, thus making them unsuitable for memory storage.
