Using Nanotechnology To Remove Blood Clots And Detect Cancer
Nanotechnology can be applied to eliminate blood clots in the human body. The objective is to develop minute robot-like structures that circulate in the bloodstream, locate the clot, and dissolve it. This capability is based on nanotechnology’s potential to manipulate individual molecules. The robots employ actuation mechanisms using piezoelectric nanofibres (PTZ). A change in electrical charge within the PTZ device produces vibrational energy actuators.
Nanotechnology may also contribute to the early detection of cancer cells and assist in their elimination. Cancer comprises a group of diseases that are characterised by abnormal cells dividing uncontrollably and infiltrating normal tissues. These cells can also disseminate throughout the body.
The control systems in the robots are located in the upper section and the tail. They are propelled by PTZ nanofibres and are guided by sinusoidal signals. Consequently, scientists can control the robots, enabling them to move to areas where blood clots are present and thereby dissolve and remove the clots from the arterioles.
The application of nanotechnology in cancer detection can occur in several ways, such as during a colonoscopy – an examination of the lining of the large intestine and rectum using a fibre-optic camera. This method allows physicians to identify and remove small polyps before they develop into cancer. The accuracy of this procedure depends on factors such as the speed with which the examination is conducted and the thoroughness with which physicians search for flat lesions.
Nanotechnology enables early detection of cancer cells or precancerous conditions before any visible tumour forms. It may also provide a method for delivering cytotoxic agents to the locations where abnormal cells are detected, thereby eliminating them and inhibiting further growth.
