What Is the Role of Nanosensors in Cancer Screening?
Nanosensors are critical in the early detection of cancer. These devices can identify cancer biomarkers at extremely low concentrations, which is crucial for early diagnosis. For instance, carbon nanotubes and silicon nanowires are used to develop sensors that can detect proteins, DNA, or RNA specific to cancer cells. By providing real-time and accurate detection, nanosensors facilitate early intervention and improve patient outcomes.
