Assessment 6:
QUESTION:
Part-A
1. What are nanoparticles?
A nanoparticle is a small particle that ranges between 1 to 100 nanometers
in size. Undetectable by the human eye, nanoparticles can exhibit
significantly different physical and chemical properties to their larger
material counterparts.
2. Mention few unique characteristics of nanoparticles.
Materials reduced la nanometer scale show unique characteristics For
instance, opaque substance become transparent (copper stable materials
turn combustible (aluminum). insoluble materials become soluble (old)
Therefore materials on nanoscale find wide applications in the field of
medicine, electronics arid in all fields of engineering
Part-B
1. Explain the applications of biomaterials.
Biomaterials may be natural or synthetic and are used in medical
applications to support, enhance, or replace damaged tissue or a biological
function. The modern field of biomaterials combines medicine, biology,
physics, and chemistry, and more recent influences from tissue engineering
and materials science.
Part-C
1. Mention few applications of nanotechnology in engineering.
Nanotechnology is being used in developing countries to help treat disease
and prevent health issues. In industry, applications may include
construction materials, military goods, and nano-machining of nano-wires,
nano-rods, few layers of graphene, etc.
2. How the nanotechnology becomes useful in the field of medicine?
One application of nanotechnology in medicine currently being developed
involves employing nanoparticles to deliver drugs, heat, light or other
substances to specific types of cells (such as cancer cells). This technique
reduces damage to healthy cells in the body and allows for earlier detection
of disease.
