Electrochemical sensors are a type of biosensor that use an electrical signal to detect specific biological molecules, including cancer markers. In cancer diagnosis, these sensors are used to detect the presence of cancer cells and monitor the progression of the disease.
The basic principle of an electrochemical sensor is to use an electrode to detect changes in the electrical signal caused by the binding of specific molecules to the electrode surface. In cancer diagnosis, specific antibodies are attached to the electrode surface to target cancer markers. When a sample containing the cancer marker is introduced, the cancer marker-antibody complex is formed, which leads to a change in the electrical signal of the electrode.This change in the electrical signal can be used to determine the presence and concentration of the cancer marker in the sample.
This change in the electrical signal can be used to determine the presence and concentration of the cancer marker in the sample. Electrochemical sensors have the potential to be highly sensitive, rapid, and cost-effective methods for cancer diagnosis. They can be used for the detection of various types of cancer, including breast cancer, prostate cancer, and lung cancer.
