Watch the video and note down the following:

-          nano inspiration from nature

-          potential of new nano structures - applications


Task 2  Reading - Nanotechnology in Medicine Application: Drug Delivery

The use of nanotechnology in medicine o_ _ _ _ _ some exciting possibilities. Some techniques are
only imagined, while others are at various stages of testing, or actually being used today.

Nanotechnology in medicine involves applications of nanoparticles currently under development, as
well as longer range research that involves the use of manufactured nano-robots to make repairs at
the cellular level (sometimes r_ _ _ _ _ _ _ to as nanomedicine).

Whatever you call it, the use of nanotechnology in the field of medicine could revolutionize the
way we detect and t_ _ _ _damage to the human body and disease in the future, and many techniques
only imagined a few years ago are making remarkable progress towards becoming realities.

One application of nanotechnology in medicine currently being developed involves employing
nanoparticles to d_ _ _ _ _ _ drugs, heat, light or other substances to specific types of cells
(such as cancer cells). Particles are engineered so that they are attracted to diseased cells,
which allows direct treatment of those cells. This technique r_ _ _ _ _ _ damage to healthy cells
in the body and allows for earlier detection of disease.

Reserchers are developing a method to release insulin that uses a sponge-like matrix that contains
insulin as well as nanocapsules containing an enzyme. When the glucose level r_ _ _ _ the
nanocapsules release hydrogen ions, which bind to the fibers making up the matrix. The hydrogen
ions make the fibers positively charged, r_ _ _ _ _ _ _ _ each other and creating openings in the
matrix through which insulin is released.
