Nanotechnology used in treatment of hepatocellular carcinoma (HCC)
Nanotechnology can be defined as the science and engineering involved in the structure ,synthesis ,characterization and application of materials and devices. A nanometer is one billionth of a meter or three sets of size smaller at that point a micron ,generally the size of an atom itself ( e,g. a DNA atom is about 2.5 nm long while a sodium molecule is about 0.2 nm(1) . The properties of materials at the nanoscale can be totally different from those at a larger scale . when the dimension of a material is decreased from an enormous size , the properties remain the same at first , then small changes happen , until finally when the size drops below 100 nm , dramatic changes in properties can happen(2) . For clarity , the term "nanotechnology" is used to define supramolecular assemblies of several to several hundered nanometers for therapeutic ( also called " nanomedicine" (3) .
Other
Nanotechnology literally means any technology on a nanoscale that has applications in the real world .This technology in treatment , imaging and drug delivery for human cells. Several studies have reported nanotechnology in the field of medicine and in treating various kinds of diseases such as cancer. This report will discuss the role of this tiny materials in treatment of hepatocellular carcinoma(HCC) and will study its hazards.
