In medicine, scientists are looking at using nanotechnology for the following:

  1. Delivering drugs with contact lenses
  2. Directing drugs to tumours with tiny “smart bombs”
  3. Gold “nano-bullets” that seek-and-destroy tumours
  4. Starving cancer with nanoparticles
  5. Deploying viruses as “nano-cameras” to explore the inner workings of cells
  6. Growing new organs from scratch

(Sounds like we may live happily ever after!)

In computing:

  1. Smaller and more powerful microchips with increased capacity
  2. Reductions in the size of hard discs
  3. Manufacturing tiny parts for computers inside bacteria (Crazy!)
  4. Quantum computing and quantum cryptography
 

In environmental science:

  1. Detecting and filtering bacteria out of water supplies
  2. Clearing heavy metal and organic chemical pollution
  3. Development of the catalytic converter which detoxifies engine fumes
  4. Smaller, more efficient batteries, advanced solar power and catalytic diesel additives

In the military:

  1. Bullet-proof battle-suits that can morph to provide camouflage or stiffen to provide splints for broken limbs
  2. Nanosensors that can detect chemical or biological dangers
