Nanotechnology

What is It?

• "Molecular Manufacturing"
• A molecule by molecule method to obtain desired configurations
• Manipulation of individual atoms and molecules
• Developed to create high performance products

Uses for Nanotechnology

• Medicine
• Fuel Cells
• The Environment
• Food

NAnomedicine

• Construction of more advanced medical instruments and devices
• Improve medical sensors for diseases and cancer
• Bring surgical control to the molecular level

Nanomedicine Cont.

• Nanoparticles: More efficient detection of Cancer Biomarkers
• Polyethylene Glycol Nanoparticles: used for therapy and imaging
• Fullerenes (Carbon based carriers): For drug delivery and photodynamics
• Magnetic Iron Oxide to be used in nanoparticles for drug delivery

Fuel Cells

• Fuel Cell: a cell producing an electric current from a chemical reaction
• Fuel Cells have membranes where only hydrogen ions pass through
• Nanotechnology: used to create more efficient membranes
• Nanotechnology: also used to create longer lasting fuel cells
• Scientists reducing amount of  platinum needed as a catalyst in fuel cells

The Environment

• Nanotechnology for clean up of pollution & finding alternate energy sources
• Silver Nanoclusters used as catalysts to reduce polluting byproducts
• Silicon Nanowires to reduce costs and creates high efficiency solar cells
• Carbon Nanotubes used in windmill blades for strength and lighter weight

Food

• Nanomaterials: to improve taste and food safety
• Silver Nanoparticles: embedded in plastic to kill bacteria more hygienic
• Clay Nanocomposties: form barrier for plastics to keep out unwanted gasses
• Carbon Nanotubes: capable of breakdown by enzymatic hydrolysis
• Edible Nanolaminate Coating: coating for food dipped in various solutions

Inventions in the future

• A Vitamin Storage System/Nanocapsules: the nutrients you need are delivered
• Nanostructures to bend light and create invisibility
• Emotion Control Devices: to control the behavior of psychopaths
• Holographic Television using nanocomposites
• "The Lifesaver Bottle": for improved purification 

Nanotech to a smaller scale?

• Picotechnology: Manipulation of matter at an even smaller scale
• Manipulation of matter at the atomic level (around 2070)
• Structure and properties of atoms altered by manipulation of energy states
