Nanotechnology has already demonstrated promising results in cancer research and treatment. Medicine has recently advanced in cancer treatment involving nanotechnology.
Nanotechnology has been used to create new and improved imaging techniques to find small tumors. Researchers have shown that incredibly small iron oxide particles (nanoparticulates) can be used with magnetic resonance imaging (MRI) to accurately detect cancers that have spread to lymph nodes, without requiring surgery.
Nanoscale drug delivery devices are being developed to deliver anticancer therapeutics specifically to tumors.
In the near future, nanoscale devices may lead to detection of the earliest stages of cancer while simultaneously delivering anticancer agents to the tumor. Early research has shown that nanoparticulate sensors can detect the cell death that occurs when a cancer cell succumbs to the effects of an anticancer drug.
Cancer and nanotechnology are pronounced together since it was proved that nanotechnology can be harnessed to kill cancer cells without harming healthy tissue.
Standard chemotherapy destroys cancer cells and normal cells alike.
New nanotechnology technique works by inserting microscopic synthetic rods called carbon nanotubules into cancer cells. When the rods are exposed to near-infra red light from a laser they heat up, killing the cell, while cells without rods are left unscathed.
