What is Nanotechnology?Nanotechnology is a relatively new technology which is the study of engineering matter on an atomic and molecular scale. Nanotechnology deals with developing materials, devices, or other structures with at least one dimension sized from 1 to 100 nanometers. Nanotechnology is considered a key technology for the future.

Development in Nanotechnology

In 2010 IBM used a silicon tip measuring only a few nanometers at its apex (tip) to chisel away material from a substrate (the under layer) to create a complete nanoscale 3D relief map of the world one-one-thousandth (0.000001x) the size of a grain of salt (approx. 1mm, meaning 1nm)— in 2 minutes and 23 seconds. This activity demonstrated a powerful patterning methodology for generating nanoscale patterns and structures as small as 15 nanometers at greatly reduced cost and complexity, opening up new prospects for fields such as electronics, optoelectronics (comb. electronics and light), and medicine..

Nanoscale

Nanoscale items are items that are measurable using nanometers. Nanomaterials are in nanoscale, with at least one dimension that is only 1 to 100 nanometers.

How does this benefit us? Find ways to save lives by finding new cures to different

disease Make drug delivery vehicles to deliver the exact amount of

drug required to a specific organ so as to reduce side-effects of the drug

Engineer tissues and regrow bones Make new materials with the properties we need Manufacture new things as substitutes of natural items Filter cleaner water and make it cleaner for us to use in our

daily lives. Clean up nuclear waste Reduce energy consumption Improve manufacturing methods Increase energy production. Place in foods so that it makes the food more healthy and

nutritious. (Biotechnology: GM Foods)

Impacts on the environment and ecosystem

Positive1. Potential nuclear waste cleaning agent.2. Find medicine and pharmaceuticals to cure diseases

in organisms.3. Create new materialsNegative1. Potential health hazards if nanomaterials are exposed

to organisms.2. There is a large amount of nanopollution (waste

product) which are radioactive and can be dangerous for its size because it can easily penetrate any animal and plant cell causing unknown effects.
