Nanotechnology enhances cancer detection through several mechanisms:
Nanosensors: These devices can detect cancer biomarkers at extremely low concentrations, which is crucial for early-stage cancer detection. Nanoparticles: Functionalized nanoparticles can target specific cancer cells, allowing for high-contrast imaging and precise localization of tumors. Quantum Dots: These semiconductor particles emit fluorescence when exposed to light, making them useful in labeling and tracking cancer cells. Nanotubes: Carbon nanotubes can be used to deliver contrast agents directly to cancer cells, improving imaging quality.
