What Types of Nanosensors Are Used in Cancer Detection?
Several types of nanosensors are being explored for cancer detection:
Gold Nanoparticles: These can be conjugated with antibodies or other ligands to target specific cancer markers. Their optical properties facilitate the detection of bound cancer cells. Carbon Nanotubes: These are used for their electrical properties and can be functionalized to detect cancer-related molecules. Quantum Dots: These semiconductor nanoparticles emit fluorescence when exposed to light, making them useful in imaging and detecting cancer cells. Magnetic Nanoparticles: These are used in magnetic resonance imaging (MRI) to enhance the contrast of cancerous tissues.
