An Approach to the Nanoparticle
Nanoparticles are colloidal, meaning it consist of a system involving small particles of one substance encapsulated in another. They are highly stable and their surface characteristics have been proven easy to manipulate .Nanoparticles absorb and emit different colors, depending on their size Nanoparticles meet the requirements of an ideal drug carrier. Nanoparticles have the capacity of extending circulation in the blood stream small enough to access to the target cells and tissues.Nanoparticles transport the active moiety into the cells easily escape from endosome-lysosome process .Nanoparticles may be constructed using biocompatible materials and ,
may be biodegradable.
Cancer
It develops when cells in a part of the body begin to grow out of control. Cancer, they all start because of out-of-control growth of abnormal cells. These abnormal cells continue to multiply, eventually outliving and out numbering normal cells. Two common types of cancer: Brain cancer and Lung cancer
Existing treatments and their side effects
Chemotherapy
Cancer treatment that has been around since the 1950s.Chemotherapy is most often mean taking medicines, or drugs, to treat cancer. Drugs are taken before or after surgery; with radiation (X-ray) treatment The side –effects resulting from nerve damage are stiff neck, head ache, nausea and vomiting, lethargy, fever, confusion,
depression etc.,
Radiation
Radiation, another common form of cancer treatment uses a stream of high-energy
particles or waves, such as x-rays, gamma rays, electrons, or protons to destroy or
damage cancer cells. Radiation therapy affects the skin, mouth, brain and lungs.
Possible Cancer treatment techniques using Nanoparticles
Magnetic Fluid Hyperthermia
Magnetic Fluid Hyperthermia technique uses nanoparticles made of iron-oxide
and coated with...
