How Does Electrochemical Detection Work in Cancer?
In the context of cancer, electrochemical detection can be used to identify and quantify specific biomarkers that are indicative of cancer. These biomarkers can include proteins, DNA, RNA, or small molecules. The process involves a few key steps:
Sample Preparation: Biological samples, such as blood or tissue, are prepared and processed to extract the target biomarkers. Electrode Functionalization: Electrodes are modified with specific recognition elements (e.g., antibodies, aptamers) that can selectively bind to the target biomarkers. Signal Generation: When the target biomarker binds to the recognition element, a chemical reaction occurs, generating an electrical signal. This signal is then measured and analyzed.
