Aptamers have shown great potential in the field of cancer diagnostics. They can be designed to bind specifically to cancer biomarkers, such as overexpressed proteins on cancer cells. This specificity makes aptamers valuable tools for early detection and diagnosis of cancer. For example, aptamers can be used in biosensors to detect cancer cells in blood samples or tissue biopsies. Because of their high sensitivity and specificity, aptamer-based diagnostic tools can provide accurate and rapid results, which are critical for early intervention and treatment.
