4 • Nanotechnology is the study of manipulating matter on an atomic scale. • Nanotechnology refers to the constructing and engineering of the functional systems at very micro level or we can say at atomic level. NANOTECHNOLOGY
Nanotechnology in Electronics Nano electronics refer to the use of nanotechnology on electronic components, especially transistors. Nano electronics often refer to transistor devices that are so small that interatomic interactions and quantum mechanical properties need to be studied extensively. Besides being small and allowing more transistors to be packed into a single chip, the uniform and symmetrical structure of nanotubes allows a higher electron mobility, a higher dielectric constant (faster frequency), and a symmetrical electron/ hole characteristic. 5
6 Increasing the density of memory chips . Decreasing the weight and thickness of the screens Nanolithography is used for fabrication of chips. Reducing the size of transistors used in integrated circuits. Improving display screens on electronics devices. R educing power consumptio ns . Advantages of using Nanotechnology in Electronics
7 Common Applications of Nano Technology Computer processing Moore’s Law describes a trend of technology. It states that the number of transistors that can be put on a single chip will double every two years.
8 Because of nanotechnology, the speed of computers has increased while the price of computing has decreased.
9 Carbon nanotubes on a glass or plastic sheet allow manufacturers to make clear conductive panels for displays that are extremely thin. Displays
10 Medical Applications Of Nanoparticles:
11 Carbon Nano tubes • These are small macromolecules that are unique for their size, shape, and have unique physical properties. Nano tubes have some special advantages over other drug delivery and diagnostic systems due to their unique physical properties . Pharmaceutical Nano systems
12 Metallic Nano particles Metallic Nano particles have used in drug delivery, especially in treatment of cancer and also in biosensors. Amongst various metals, silver and gold Nano particles are of prime importance for biomedical use.
13 Carbon Nano tubes Metallic Nano particles
14 These have been extensively explored and most developed Nano carriers for novel and targeted drug delivery due to their small size, these are 50-200 nm in size . When dry phospholipids are hydrated, closed vesicles are formed . Liposomes are biocompatible, versatile and have good entrapment efficiency. It finds application as long circulatory and in passive and active delivery of gene, protein and peptide . Liposomes:
15 Liposomes
• Cancer is an uncontrolled division/proliferation of cells. • The 10 to 100 nm small size of nanoparticles, allows them to preferentially accumulate at tumor sites. 16 Cancer
17 Nano wires are used to prepare sensor test chips, which can detect proteins and other biomarkers left behind by cancer cells. Nano shells of 120 nm diameter, coated with gold were used to kill cancer tumors in mice. Cadmium selenide Nano particles in the form of quantum dots are used in detection of cancer tumors because when exposed to ultraviolet light, they glow.
