Definition of Nanotechnology - Nanotechnology is the construction and use of functional structures at an atomic or molecular scale that is measured in nanometers.

Nanotechnology Applications -

1. Tennis Ball - An example of nanotechnology being applied to our world today is in this special tennis ball created by Wilson. Wilson's Double Core tennis ball has a nanocomposite coating that keeps the ball bouncy for a longer period of time. The nanoparticles in the ball acts a sealant making it difficul for air to escape the ball.

2. Food - "Nanofood" is when nanoparticles, nanotechnology techniques or tools are used during cultivation, production, processing, or packaging. They silicate nanoparticles to provide a barrier to gasses or moisture in a plastic film used for packaging.

3. Medicine - Nanotechnology are becoming used in diagnostic testing to locate cancer tumors and other diseases. With the advancement of nanotechnology in detecting diseases, this will give patients faster and more accurate results and treatment.

Uses of Silver Particles -

1. Optical Appliction - The silver nanoparticles are used to efficiently harvest light and for enhanced optical spectroscopies for things such as contact lenses, glasses and sunglasses.

2. Antibacterial Applications- The silver nanoparticles are incorpoated in apparel, footwear, paints, wound dressings, appliances, cosmetics, and platics for their antibacterial properties.

3. Electronical Applications- The silver nanoparticles are used in various eletronic products such as: printing, memory, storage, and many other products.

Drawbacks of Silver Nanoparticles-

Nanoparticles are small enough to be absorbed through the skin which could cause irritation. Possibility that as catalysts, Nanoparticles may speed up reactions in living things in unpredicting ways, perhaps causing illness or death. Silver Nanoparticles kill bacteria but may kill "good" bacteria if ingested or inhaled. Breathing in silver Nanoparticles could potentially cause lung damage, cancer, and many other things. They are also costly to produce. Silver nanoparticles are bacteriostatic, meaning that they limit the growth of bacteria. This may result in the destruction of bacteria that help in breaking down the organic matter in water treatment plants.
