Nanotechnology:
The engineering of functional systems at the molecular scale. The nano-structure has special properties that are exclusively due to its nanoscale proportions. the understanding and control of matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. This covers both current work and concepts that are more advanced.

Applications of Nanoparticles:

1. Bone Cement- protective bone cement for hip and knee joint replacement
2. Antibacterial- wounds dressings, appliances, and cosmetics
3. Samsung Appliances- emit silver nanoparticles.
4. Batteries- Companies are currently developing batteries using nanomaterials.

Uses of Silver Nanoparticles:
1. Helped to prevent bacteria growth in food processessing and packaging.
2. Body tissue may repair itself with the help of nanotechnology
3. Silver nanoparticles are incorporated in apparel, footwear, paints, wound dressings, appliances, cosmetics, and plastics for their antibacterial properties.
4. Silver nanoparticles are used in conductive inks and integrated into composites to enhance thermal and electrical conductivity.

Drawback to Silver Nanoparticles:
Silver nanopartciles are bacteriostatic (limit the growth of bacteria) can result in the destruction of bacteria that help in the breaking down the organic matter in water treatment plants.
