Question

explain and describe with examples The role of Nanotechnology in Healthcare

Answer 1

Nanotechnology is the study, design, creation, synthesis, manipulation, and application of materials, devices, and systems at the nanometre scale.

One application of nanotechnology in healthcare are employing nanoparticles to deliver 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 reduces damage to healthy cells in the body and allows for earlier detection of disease.

Using antibodies attached to carbon nanotubes in chips to detect cancer cells in the blood stream. This method could be used in simple lab tests that could provide early detection of cancer cells in the bloodstream.

A test for early detection of kidney damage . The method uses gold nanorods functionalized to attach to the type of protein generated by damaged kidneys. When protein accumulates on the nanorod the color of the nanorod shifts. The test is designed to be done quickly and inexpensively for early detection of a problem.
