Нанотехнология использует практические методы исследования, анализа и синтеза, а также методы производства и применения продуктов с заданной атомной структурой путём контролируемого манипулирования отдельными атомами и молекулами. Современная наука показала, что вещество может иметь совершенно новые свойства, если взять его очень маленькую частицу. Частицы размерами от 1 до 100 нанометров обычно называют «наночастицами». Наночастицы некоторых материалов обладают очень хорошими каталитическими и адсорбционными свойствами. Другие материалы показывают удивительные оптические свойства, например, сверхтонкие пленки органических материалов применяются для производства солнечных батарей.

Inorganic nanomaterials, (e.g. quantum dots, nanowires and nanorods) because of their interesting optical and electrical properties, could be used in optoelectronics. Nanoparticles or nanocrystals made of metals, semiconductors, or oxides are of particular interest for their mechanical, electrical, magnetic, optical, chemical and other properties. Nanoparticles have been used as quantum dots and as chemical catalysts such as nanomaterial-based catalysts. Recently, a range of nanoparticles are extensively investigated for biomedical applications including tissue engineering, drug delivery, biosensor. Nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic or molecular structures. A bulk material should have constant physical properties regardless of its size, but at the nanoscale this is often not the case. https://en.wikipedia.org/wiki/Nanomaterials
