In fact,   the application of nanotechnology in medicine in relation to the timely identification and root cause of cancer is the focus of research activities worldwide. 

Nanotechnology offers a design that can integrate research in to the structure and function of proteins and their way of functioning and interactions within cells with other scientific studies and to understand the causes of cancer at the molecular level.

The use of nanoparticles in the treatment of cancer cells

 Using these nanoparticles as a drug to treat malignant cancer cells has no adverse effect on healthy cells and tissues of the body.

Once these nanoparticles reach the tumors,the drugs inside them are activated by narrow bands of laser light.

These nanoparticles are also able to determine the effect of treatment on malignant cells.

The great idea of just diagnosing , treating  and reporting on the effectiveness of treatment can only be achieved with thev help of nanotechnology.

Nanoparticles used in the treatment of cancer are divided into the following groups:

Nano holes are small holes that allow for the passage of only one strand of DNA and are used to detect DNA changes in cancer.

Quantum dots are also used to increase the sensitivity of laboratory methods of cancer detection.

These molecules are highly capable of being identified and treat simultaneously,

And have a broad surface that enables them to bind therapeutic agents or other biologically active molecules. 

Nano-shells are a structure with a centrall core on which a thin membrane of a metal such as gold is coated and can be thermally destroyed or imaged using an outer laser and delivering energy to the nano-shells in a tumors.it is used for wound healing.

The group is magnetic nanoparticles whose iron oxide is a major component of magnetic nanoparticles.The most important adventage of using these particlesis smaller than 100 nm .

With the helps of a magnetic field,these particles can be directed to a specific area,Which facilitates imaging for the diagnosis and treatment of cancer.
