Cancer is a class of diseases characterized by out-of-

control cell growth .

Nanomedicine is the medical application of

nanotechnology

Page 5: Cancer Hyperthermia part2

In nanotechnology, a particle is defined as a small

object that behaves as a whole unit in terms of its

transport and properties .

Page 6: Cancer Hyperthermia part2

Magnetic nanoparticles are a class of

nanoparticles which can be manipulated using

magnetic field .

Page 7: Cancer Hyperthermia part2

Magnetic hyperthermia:Magnetic nanoparticles are used in an experimental

cancer treatment called magnetic hyperthermia in which the fact that nanoparticles heat when they are

placed in an alternative magnetic field is used.

Cytotoxicity (Tissue Culture)

Cell culture assays are used to assess the

biocompatibility of a material or extract through

the use of isolated cells in vitro.

These techniques are useful in evaluating the

toxicity or irritancy potential of materials and

chemicals.

They provide an excellent way to screen

materials prior to in vivo tests.
